The Last Big Hurdle: How to Prepare for a Successful PhD Defence

It’s the moment almost everyone who completes a PhD both dreads and looks ahead to for years—the defence. It signals a major achievement, but in people’s imaginations, it can seem like the stuff of nightmares… standing frozen in front of everyone, unable to answer a tricky question posed by a committee member and feeling like you must look incompetent. The format of a doctoral defence varies from field to field, but the worst fears of the candidates remain largely the same. Though most people know it probably won’t go so badly, the open-ended-ness can certainly be intimidating- you’re up there alone in front of a panel of experts who get to ask you whatever they’d like, and you may have to deliver your answers in front of an audience of your peers. There are few experiences in academic life more geared to be stressful for the person at the centre of them.

It doesn’t have to be that bad. I spent the weeks leading up to my PhD defence in a state of near panic, but I can honestly say that once it actually got underway, I sort of enjoyed it. You’re the star of the show and get to walk your peers through the finer points of your research. It can be a really invigorating experience. So let’s try to break this down into bite-sized chunks and look at strategies and tips for making your defence an event you might actually look back fondly on.

What the committee wants

Let’s start with what the committee is actually looking for. They want to see a firm grasp of the subject matter, an understanding of the implications of the work, and the ability to see weaknesses in the methodology and possible routes to take for future work. This means creating a presentation that gives a clear, logical overview of your topic, the question you’re addressing, what you did, your results and conclusions, and where the research can go from here. Remember, your jury members are not out to get you. The questions you receive from them will generally fall under one of three headings- those that test your subject knowledge, those that clarify a confusing point, and those that arise from genuine curiosity. If your presentation does a good job of conveying your knowledge of your topic, you can expect more questions from the second and third categories, allowing you to think of the defense more as a conversation amongst experts than a test from on high.

How to prepare

Practice is obviously very important here. Once you’ve put your talk together, find a trusted friend or mentor (ideally, several of them) who knows your field to go through it with you. They can both help you to pare down unnecessary parts and point out logical leaps you may not have noticed because you’re so close to the subject matter. You also want this to be a person who will ask you tough questions and try to spot holes in your reasoning, so choose your test audience carefully. It can be tempting to spend a lot of time obsessing over your slides, trying to make them perfect, but there’s a lot of studying you’ll need to do to be ready for more tangential questions, so don’t lose too much time this way.

Even though you have lived and breathed your thesis topic for years, it’s a good idea to give your thesis a complete re-read just to make sure you really know what’s in there. It may have been months since you finished writing it, and parts may have gotten a little fuzzy since then. Make sure you know why you used the methodology that you did, be able to justify any conclusions you’ve made, and if there are mistakes, admit them openly at the defence and be able to talk about what you should have done differently—the committee isn’t looking for perfection, they’re looking for clear thinking and thorough consideration of methodology.

This is also a good time to review important topics that are peripheral to your work; this will allow you to answer some of the questions designed to test the limits of your broader knowledge of your field. One of the best pieces of defence preparation advice I’ve ever heard is to find out what each of your committee members’ professional interests are, and do a bit of reading on those topics. There’s a very good chance that they’ll ask you something that’s related to their own work, because that’s familiar ground to them, and you may be able to anticipate these questions this way.

Finally, though it’s less and less of a problem as technology improves, you’ll want to make very sure ahead of time that all your presentation gear works and connects properly to the display equipment in the room where your defence will be. No one wants to be running around at the last moment looking for a dongle they didn’t think they needed, or have their laptop’s battery run out partway through the defence. Check that your slides look the same way on the projection screen as they do on your computer- not cut off or too dark. It also doesn’t hurt just to spend time in the room in which you’ll be presenting, to get a feel for the place and see where everything will be positioned.

Common questions and ideas to think about

• What makes your project original, and how does it answer a previously unanswered question? What have you contributed to the body of knowledge on this topic?
• Why was this question important to ask? Why do we care about what your findings reveal? (Hint: “Just for the sake of knowing” is not an acceptable answer here.)
• Did the focus of your project change over its course? If so, explain how and why.

Methodology

• Why did you choose your methodological approach (including your statistical analyses)? Why is it superior to or more appropriate than all other methodologies?
• Talk about the difficulties you experienced with your methodology and how you addressed them.
• What are the limitations of your study design/methodology?
• Explain how your data represent an appropriate source of measurement to address your question.
• Is the amount of data gathered sufficient to address your question? Why or why not?
• If you could do it again with unlimited time and funds, how would your methodology change?

Conclusions

• What would you say is the most important “take-away” message of your work?
• Does your work have wider implications for other disciplines in your field?
• How do your conclusions support or contradict the existing literature?
• Are there alternative ways your data could have been interpreted?
• Speculate about what broader implications your research could have, but which aren’t addressed by your data, or were outside the scope of your project.
• If you were to continue on with this area of research, what would you do next to further your results? Is there a closely related “spin-off” question that needs to be answered?
• Propose an experimental design to test this related question. What results might you expect to see?
• Where do you think this field of study is headed in the next five to ten years?

Tips, tricks, and stress management

• Practice the first few minutes of your talk until you can do it on ‘autopilot’; this will give you a bit of time to relax into your presentation, get your thoughts in order, and begin talking more confidently.
• If your defence is open to the public, ask a few supportive friends or colleagues to sit where you can easily make eye contact while you’re talking. Seeing a friendly, smiling face can be encouraging and help you to relax.
• Don’t forget to review the newest literature in the weeks leading up to your defence—one or more important papers may have been published in your field since you wrote your thesis, and you’ll want to know about them.
• Have a hard copy of your thesis on hand during the defence. It’s much faster to flip to a physical page when asked about a particular section of the text. If this really isn’t for you, be sure you have a quick way to move through pages on your computer.
• Eat and drink the same things you normally would on the day of your defence. Your stomach may be extra sensitive in response to the stress, and you don’t want to surprise it with anything new. And go easy on the caffeine… jittery-ness will not help you to manage your stress!
• Try to let your enthusiasm for your subject matter show; your audience will feel more positive about your talk if they can see that you really find the work fascinating.
• It’s fine to take a moment to think about your answer before responding. The silence isn’t as long or as deafening as you think it is. And if you don’t know, just admit you don’t know—it’s okay to not know everything.
• Dress well, but comfortably, and try to project confidence. If you can speak to your committee as a group of your peers, it will reflect well on your growth as a scientist in training- and demonstrate you are someone who deserves to be awarded their doctorate.
• Don’t forget to publicly thank your advisor, your committee, and any other key people involved with your project for their time commitment and investment in your career.
• When planning post-defence festivities, be aware that you may be more tired, both mentally and emotionally, than you expected. Don’t ask too much of yourself in the hours following the event.

A bit of encouragement

Above all, there are two things you need to remember while preparing for your defence. First, your advisor and committee would not have allowed you to proceed to this point if they didn’t think you were ready. They want to see you succeed and, altruism aside, it would reflect badly on them as well if you were to fail. Trust that they’ve made the right decision. Second, after years of delving into your little corner of the scientific world, no one knows your thesis topic better than you do—not even your committee. Marshall your facts and feel confident in knowing that on this topic, you’re the world expert.

How to prepare an excellent thesis defense

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

In essence, the PhD defence is more than a ceremonial checkpoint—it is a transformative experience that validates the intellectual journey, underscores the significance of scholarly contributions, and sets the stage for a continued legacy of academic excellence. As we navigate the intricacies of this process, we invite you to explore the multifaceted dimensions that make the PhD defence an indispensable chapter in the narrative of academic achievement.

What is a PhD Defence?

At its core, a PhD defence is a rigorous and comprehensive examination that marks the culmination of a doctoral candidate’s research journey. It is an essential component of the doctoral process in which the candidate is required to defend their dissertation before a committee of experts in the field. The defence serves multiple purposes, acting as both a showcase of the candidate’s work and an evaluative measure of their understanding, critical thinking, and contributions to the academic domain.

The primary goals of a PhD defence include:

• Presentation of Research: The candidate presents the key findings, methodology, and significance of their research.
• Demonstration of Mastery: The defence assesses the candidate’s depth of understanding, mastery of the subject matter, and ability to engage in scholarly discourse.
• Critical Examination: Committee members rigorously question the candidate, challenging assumptions, testing methodologies, and probing the boundaries of the research.
• Validation of Originality: The defence validates the originality and contribution of the candidate’s work to the existing body of knowledge.

The PhD defence often takes the form of an oral examination, commonly referred to as the viva voce. This oral component adds a dynamic and interactive dimension to the evaluation process. Key elements of the oral examination include:

• Presentation: The candidate typically begins with a formal presentation, summarizing the dissertation’s main components, methodology, and findings. This presentation is an opportunity to showcase the significance and novelty of the research.
• Questioning and Discussion: Following the presentation, the candidate engages in a thorough questioning session with the examination committee. Committee members explore various aspects of the research, challenging the candidates to articulate their rationale, defend their conclusions, and respond to critiques.
• Defence of Methodology: The candidate is often required to defend the chosen research methodology, demonstrating its appropriateness, rigour, and contribution to the field.
• Evaluation of Contributions: Committee members assess the originality and impact of the candidate’s contributions to the academic discipline, seeking to understand how the research advances existing knowledge.

The oral examination is not a mere formality; it is a dynamic exchange that tests the candidate’s intellectual acumen, research skills, and capacity to contribute meaningfully to the scholarly community.

In essence, the PhD defence is a comprehensive and interactive evaluation that encapsulates the essence of a candidate’s research journey, demanding a synthesis of knowledge, clarity of expression, and the ability to navigate the complexities of academic inquiry. As we delve into the specifics of the defence process, we will unravel the layers of preparation and skill required to navigate this transformative academic milestone.

How Long is a PhD Defence?

The duration of a PhD defence can vary widely, but it typically ranges from two to three hours. This time frame encompasses the candidate’s presentation of their research, questioning and discussions with the examination committee, and any additional deliberations or decisions by the committee. However, it’s essential to note that this is a general guideline, and actual defence durations may vary based on numerous factors.

• Sciences and Engineering: Defenses in these fields might lean towards the shorter end of the spectrum, often around two hours. The focus is often on the methodology, results, and technical aspects.
• Humanities and Social Sciences: Given the theoretical and interpretive nature of research in these fields, defences might extend closer to three hours or more. Discussions may delve into philosophical underpinnings and nuanced interpretations.
• Simple vs. Complex Studies: The complexity of the research itself plays a role. Elaborate experiments, extensive datasets, or intricate theoretical frameworks may necessitate a more extended defence.
• Number of Committee Members: A larger committee or one with diverse expertise may lead to more extensive discussions and varied perspectives, potentially elongating the defence.
• Committee Engagement: The level of engagement and probing by committee members can influence the overall duration. In-depth discussions or debates may extend the defence time.
• Cultural Norms: In some countries, the oral defence might be more ceremonial, with less emphasis on intense questioning. In others, a rigorous and extended defence might be the norm.
• Evaluation Practices: Different academic systems have varying evaluation criteria, which can impact the duration of the defence.
• Institutional Guidelines: Some institutions may have specific guidelines on defence durations, influencing the overall time allotted for the process.

Candidates should be well-prepared for a defence of any duration. Adequate preparation not only involves a concise presentation of the research but also anticipates potential questions and engages in thoughtful discussions. Additionally, candidates should be flexible and responsive to the dynamics of the defense, adapting to the pace set by the committee.

Success Factors in a PhD Defence

• Successful defence begins with a deep and comprehensive understanding of the research. Candidates should be well-versed in every aspect of their study, from the theoretical framework to the methodology and findings.
• Thorough preparation involves anticipating potential questions from the examination committee. Candidates should consider the strengths and limitations of their research and be ready to address queries related to methodology, data analysis, and theoretical underpinnings.
• Conducting mock defences with peers or mentors can be invaluable. It helps refine the presentation, exposes potential areas of weakness, and provides an opportunity to practice responding to challenging questions.
• Actively listen to questions without interruption. Understanding the nuances of each question is crucial for providing precise and relevant responses.
• Responses should be clear, concise, and directly address the question. Avoid unnecessary jargon, and strive to convey complex concepts in a manner that is accessible to the entire committee.
• It’s acceptable not to have all the answers. If faced with a question that stumps you, acknowledge it honestly. Expressing a willingness to explore the topic further demonstrates intellectual humility.
• Use questions as opportunities to reinforce key messages from the research. Skillfully link responses back to the core contributions of the study, emphasizing its significance.
• Rehearse the presentation multiple times to build familiarity with the material. This enhances confidence, reduces nervousness, and ensures a smooth and engaging delivery.
• Maintain confident and open body language. Stand tall, make eye contact, and use gestures judiciously. A composed demeanour contributes to a positive impression.
• Acknowledge and manage nervousness. It’s natural to feel some anxiety, but channelling that energy into enthusiasm for presenting your research can turn nervousness into a positive force.
• Engage with the committee through a dynamic and interactive presentation. Invite questions during the presentation to create a more conversational atmosphere.
• Utilize visual aids effectively. Slides or other visual elements should complement the spoken presentation, reinforcing key points without overwhelming the audience.
• View the defence not only as an evaluation but also as an opportunity for continuous improvement. Feedback received during the defence can inform future research endeavours and scholarly pursuits.

In essence, success in a PhD defence hinges on meticulous preparation, adept handling of questions, and projecting confidence and composure during the presentation. A well-prepared and resilient candidate is better positioned to navigate the challenges of the defence, transforming it from a moment of evaluation into an affirmation of scholarly achievement.

Failure in PhD Defence

• While the prospect of failing a PhD defence is relatively rare, it’s essential for candidates to acknowledge that the possibility exists. Understanding this reality can motivate diligent preparation and a proactive approach to mitigate potential risks.
• Failure, if it occurs, should be seen as a learning opportunity rather than a definitive endpoint. It may highlight areas for improvement and offer insights into refining the research and presentation.
• Lack of thorough preparation, including a weak grasp of the research content, inadequate rehearsal, and failure to anticipate potential questions, can contribute to failure.
• Inability to effectively defend the chosen research methodology, including justifying its appropriateness and demonstrating its rigour, can be a critical factor.
• Failing to clearly articulate the original contributions of the research and its significance to the field may lead to a negative assessment.
• Responding defensively to questions, exhibiting a lack of openness to critique, or being unwilling to acknowledge limitations can impact the overall impression.
• Inability to address committee concerns or incorporate constructive feedback received during the defense may contribute to a negative outcome.
• Comprehensive preparation is the cornerstone of success. Candidates should dedicate ample time to understanding every facet of their research, conducting mock defences, and seeking feedback.
• Identify potential weaknesses in the research and address them proactively. Being aware of limitations and articulating plans for addressing them in future work demonstrates foresight.
• Engage with mentors, peers, or advisors before the defence. Solicit constructive feedback on both the content and delivery of the presentation to refine and strengthen the defence.
• Develop strategies to manage stress and nervousness. Techniques such as mindfulness, deep breathing, or visualization can be effective in maintaining composure during the defence.
• Conduct a pre-defense review of all materials, ensuring that the presentation aligns with the dissertation and that visual aids are clear and supportive.
• Approach the defence with an open and reflective attitude. Embrace critique as an opportunity for improvement rather than as a personal affront.
• Clarify expectations with the examination committee beforehand. Understanding the committee’s focus areas and preferences can guide preparation efforts.
• In the event of failure, candidates should approach the situation with resilience. Seek feedback from the committee, understand the reasons for the outcome, and use the experience as a springboard for improvement.

In summary, while the prospect of failing a PhD defence is uncommon, acknowledging its possibility and taking proactive steps to mitigate risks are crucial elements of a well-rounded defence strategy. By addressing common failure factors through thorough preparation, openness to critique, and a resilient attitude, candidates can increase their chances of a successful defence outcome.

PhD Defense or Defence?

• The choice between “defense” and “defence” is primarily a matter of British English versus American English spelling conventions. “Defense” is the preferred spelling in American English, while “defence” is the British English spelling.
• In the global academic community, both spellings are generally understood and accepted. However, the choice of spelling may be influenced by the academic institution’s language conventions or the preferences of individual scholars.
• Academic institutions may have specific guidelines regarding language conventions, and candidates are often expected to adhere to the institution’s preferred spelling.
• Candidates may also consider the preferences of their advisors or committee members. If there is a consistent spelling convention used within the academic department, it is advisable to align with those preferences.
• Consideration should be given to the spelling conventions of scholarly journals in the candidate’s field. If intending to publish research stemming from the dissertation, aligning with the conventions of target journals is prudent.
• If the defense presentation or dissertation will be shared with an international audience, using a more universally recognized spelling (such as “defense”) may be preferred to ensure clarity and accessibility.
• Regardless of the chosen spelling, it’s crucial to maintain consistency throughout the document. Mixing spellings can distract from the content and may be perceived as an oversight.
• In oral presentations and written correspondence related to the defence, including emails, it’s advisable to maintain consistency with the chosen spelling to present a professional and polished image.
• Recognizing that language conventions can vary, candidates should approach the choice of spelling with flexibility. Being adaptable to the preferences of the academic context and demonstrating an awareness of regional variations reflects a nuanced understanding of language usage.
• With the increasing globalization of academia, an awareness of language variations becomes essential. Scholars often collaborate across borders, and an inclusive approach to language conventions contributes to effective communication and collaboration.

In summary, the choice between “PhD defense” and “PhD defence” boils down to regional language conventions and institutional preferences. Maintaining consistency, being mindful of the target audience, and adapting to the expectations of the academic community contribute to a polished and professional presentation, whether in written documents or oral defences.

Is PhD Defense a Formality?

• While the PhD defence is a structured and ritualistic event, it is far from being a mere formality. It is a critical and substantive part of the doctoral journey, designed to rigorously evaluate the candidate’s research contributions, understanding of the field, and ability to engage in scholarly discourse.
• The defence is not a checkbox to be marked but rather a dynamic process where the candidate’s research is evaluated for its scholarly merit. The committee scrutinizes the originality, significance, and methodology of the research, aiming to ensure it meets the standards of advanced academic work.
• Far from a passive or purely ceremonial event, the defence involves active engagement between the candidate and the examination committee. Questions, discussions, and debates are integral components that enrich the scholarly exchange during the defence.
• The defence serves as a platform for the candidate to demonstrate the originality of their research. Committee members assess the novelty of the contributions, ensuring that the work adds value to the existing body of knowledge.
• Beyond the content, the defence evaluates the methodological rigour of the research. Committee members assess whether the chosen methodology is appropriate, well-executed, and contributes to the validity of the findings.
• Successful completion of the defence affirms the candidate’s ability to contribute meaningfully to the academic discourse in their field. It is an endorsement of the candidate’s position as a knowledgeable and respected scholar.
• The defence process acts as a quality assurance mechanism in academia. It ensures that individuals awarded a doctoral degree have undergone a thorough and rigorous evaluation, upholding the standards of excellence in research and scholarly inquiry.
• Institutions have specific criteria and standards for awarding a PhD. The defence process aligns with these institutional and academic standards, providing a consistent and transparent mechanism for evaluating candidates.
• Successful completion of the defence is a pivotal moment that marks the transition from a doctoral candidate to a recognized scholar. It opens doors to further contributions, collaborations, and opportunities within the academic community.
• Research presented during the defence often forms the basis for future publications. The validation received in the defence enhances the credibility of the research, facilitating its dissemination and impact within the academic community.
• Beyond the academic realm, a successfully defended PhD is a key credential for professional advancement. It enhances one’s standing in the broader professional landscape, opening doors to research positions, teaching opportunities, and leadership roles.

In essence, the PhD defence is a rigorous and meaningful process that goes beyond formalities, playing a crucial role in affirming the academic merit of a candidate’s research and marking the culmination of their journey toward scholarly recognition.

Dressing for Success: PhD Defense Outfit

• For Men: A well-fitted suit in neutral colours (black, navy, grey), a collared dress shirt, a tie, and formal dress shoes.
• For Women: A tailored suit, a blouse or button-down shirt, and closed-toe dress shoes.
• Dress codes can vary based on cultural expectations. It’s advisable to be aware of any cultural nuances within the academic institution and to adapt attire accordingly.
• With the rise of virtual defenses, considerations for attire remain relevant. Even in online settings, dressing professionally contributes to a polished and serious demeanor. Virtual attire can mirror what one would wear in-person, focusing on the upper body visible on camera.
• The attire chosen for a PhD defense contributes to the first impression that a candidate makes on the examination committee. A professional and polished appearance sets a positive tone for the defense.
• Dressing appropriately reflects respect for the gravity of the occasion. It acknowledges the significance of the defense as a formal evaluation of one’s scholarly contributions.
• Wearing professional attire can contribute to a boost in confidence. When individuals feel well-dressed and put-together, it can positively impact their mindset and overall presentation.
• The PhD defense is a serious academic event, and dressing professionally fosters an atmosphere of seriousness and commitment to the scholarly process. It aligns with the respect one accords to academic traditions.
• Institutional norms may influence dress expectations. Some academic institutions may have specific guidelines regarding attire for formal events, and candidates should be aware of and adhere to these norms.
• While adhering to the formality expected in academic settings, individuals can also express their personal style within the bounds of professionalism. It’s about finding a balance between institutional expectations and personal comfort.
• Select and prepare the outfit well in advance to avoid last-minute stress. Ensure that the attire is clean, well-ironed, and in good condition.
• Accessories such as ties, scarves, or jewelry should complement the outfit. However, it’s advisable to keep accessories subtle to maintain a professional appearance.
• While dressing professionally, prioritize comfort. PhD defenses can be mentally demanding, and comfortable attire can contribute to a more confident and composed demeanor.
• Pay attention to grooming, including personal hygiene and haircare. A well-groomed appearance contributes to an overall polished look.
• Start preparation well in advance of the defense date. Know your research inside out, anticipate potential questions, and be ready to discuss the nuances of your methodology, findings, and contributions.
• Conduct mock defenses with peers, mentors, or colleagues. Mock defenses provide an opportunity to receive constructive feedback, practice responses to potential questions, and refine your presentation.
• Strike a balance between confidence and humility. Confidence in presenting your research is essential, but being open to acknowledging limitations and areas for improvement demonstrates intellectual honesty.
• Actively engage with the examination committee during the defense. Listen carefully to questions, respond thoughtfully, and view the defense as a scholarly exchange rather than a mere formality.
• Understand the expertise and backgrounds of the committee members. Tailor your presentation and responses to align with the interests and expectations of your specific audience.
• Practice time management during your presentation. Ensure that you allocate sufficient time to cover key aspects of your research, leaving ample time for questions and discussions.
• It’s normal to feel nervous, but practicing mindfulness and staying calm under pressure is crucial. Take deep breaths, maintain eye contact, and focus on delivering a clear and composed presentation.
• Have a plan for post-defense activities. Whether it’s revisions to the dissertation, publications, or future research endeavors, having a roadmap for what comes next demonstrates foresight and commitment to ongoing scholarly contributions.
• After successfully defending, individuals often emphasize the importance of taking time to reflect on the entire doctoral journey. Acknowledge personal and academic growth, celebrate achievements, and use the experience to inform future scholarly pursuits.

In summary, learning from the experiences of others who have successfully defended offers a wealth of practical wisdom. These insights, combined with thoughtful preparation and a proactive approach, contribute to a successful and fulfilling defense experience.

From Nerves to Triumph: Your Personal Guide to Dissertation Defense

• August 26, 2023
• Aberystwyth University
• Dissertation Defence/ Viva , Mental Health , Thesis and Dissertation , Thesis Tips , Wellbeing

Picture this: after countless hours of research, writing, and refining, you’re now standing on stage with your cohort, in a gown and funny hat, because … you’ve finally completed that last important milestone in your academic journey – defending your doctoral dissertation. It’s a culmination of years of dedication, determination, and sleepless nights.     You’re not there yet—but you’re close. So how do you make it past this final, nerve-wracking hurdle?  

In this article, we’ll deep-dive into the dissertation defense process, with tips, strategies, and straight-up information. I’ll share my expertise as a coach whose job it is to get people up on that stage.  

What to expect during the dissertation defense

A dissertation defense typically consists of an oral presentation to your dissertation committee, who have already received and read the final draft of your dissertation manuscript. Other members of your cohort and institution, and outside readers or experts, might also be present in the audience.  

Without fail, I see two different reactions to this news from my coaching students: either they are terrified of having their work scrutinized by their committee in public, or they are extremely laid back, knowing that they’ve already done all the hard work in the manuscript. (These later students are the ones paying attention to me).  

You probably already know the general gist of what happens in a defense presentation: you present the highlights of your study, the committee ask questions, and then they vote on whether you pass or need to complete further revision. So, here are some things you might not yet know:

• The oral defense gives the committee the opportunity to ask you about any areas of your study that are still unclear or weak on paper – so that you can prove they are not unclear or weak in real life. In other words, it’s a chance to get anything that got stuck in your head (rather than making it on to paper) out and in front of your committee.

• Your chair or supervisor and committee should not be allowing you to complete the defense process unless they are already confident that the biggest issues with your work have already been resolved.

• Questions are normal – your committee are working with you because your work interests them (hopefully), so questions are as likely to indicate their excitement about your work as a problem they have spotted.

• Revisions are normal – from requests to polish the grammar to insisting you add more supporting sources or develop your recommendations more thoroughly, “pass with revisions” is a normal, common, and expected end result. To pass with no revisions is pretty rare (although I have had a few students achieve this – looking at you, YY!) – like getting 100% on a calculus test in school.

In short, your defense presentation is nothing to be scared of. You are lined up for defense because both you and your committee feel you know your stuff, and now all you need to do is share what you’ve produced and learned and engage people in discussion about it. You got this!

Preparing for Your Dissertation Defense

Still nervous? Ok, that’s fair enough. As with many things, good preparation can help you get those nerves under control, so here are some top tips to help you get ready.

Tick the Boxes

It’s essential to understand the requirements and expectations of your defense committee. Get familiar with the specific guidelines and procedures set by your institution, and make sure you meet all necessary criteria. If you’re giving them what they ask for, you are definitely off to a strong start.

Know Your Stuff

This defense is about you showing off what you know, so before you stand up in front of the crown, take a deep dive into your own research masterpiece. Thoroughly review your dissertation, scrutinizing each chapter, section, and argument. Make notes. Look for anything that might provoke questions or debate. Remember, this is your opportunity to showcase your expertise and demonstrate the depth of your knowledge.

Seek Wise Counsel

Your advisor and committee members are the best resources you could ask for about defense. They set the guidelines, and they judge whether you have done well. Reach out to them for guidance, feedback, and advice—their collective wisdom and support can be instrumental in honing your presentation. And, if they are not all that … well, remember there are others out there who can help, including coaches, mentors, and past students.

Just like any performance, practice makes perfect. Take the time to rehearse your presentation multiple times, refining your delivery and strengthening your command over the content. By doing so, you’ll build confidence and ensure a smoother delivery when the day arrives. Even more importantly, you’ll settle the key points of your study firmly in your brain, making sure you sound like the expert you are.

Anticipate the Unknown

Obviously, you can’t predict every question or comment that will come up during your defense. However, you can still prepare yourself for potential challenges. Get cozy with the research landscape in your field and the interests of your committee members. Step outside of your own perspective and view your work through a stranger’s eyes to anticipate areas of critique or alternative viewpoints. This will enable you to respond thoughtfully and demonstrate your ability to engage in scholarly discourse.

Managing Nerves and Anxiety

You know what’s coming and you know how to prepare – are you still nervous? If so, know that that is completely normal. Here’s how me and two of my students got their dissertation defense nerves under control.

An Awesome Supervisor

For my own dissertation defense (known as a viva voce in the UK), I was incredibly lucky to have a supervisor with whom I had a strong, supportive, and nurturing relationship. Although the main examination of my work was handled by the external reader, who sat across from me behind a big desk, my supervisor sat behind him and nodded and smiled encouragingly every time I said something. Words can’t describe how much that calmed me down and gave me confidence. If you are as lucky as me and have an awesome supervisor, tell your nerves they can stand down – your supervisor’s got your back!

You Can Get Used to Anything

One of my students, who graduated last year, suffered from terrible defense nerves because she was worried about holding so much complex information in her head and delivering it coherently. Her solution? She practiced endlessly, over the course of about a month.

With me as her coach playing the role of audience, or with her kids and other family members, her cohort peers, her dog, and even other academics, she presented that study until she could do so in her sleep. The point was that, by the time the actual defense day rolled around, presenting the study to people was comfortable, familiar territory. Done and dusted!

Temporary Denial

Another student, who graduated shortly after, took completely the opposite approach to managing dissertation defense nerves. This student was burnt out from a huge rush to meet an unexpectedly tight deadline for the final manuscript when her chair decided to retire at the last minute. Rather than burn herself out further, she hit send on the manuscript, paid a designer to polish the design of the presentation rough draft, and then shut down her devices and went on holiday with her family. For one week, she did not look at or talk about her research at all. Instead, she sat on the beach, ate ice cream, and scrolled Instagram (probably). Then, she returned to work (a week before the presentation), refreshed and feeling excited about her work again. The break enabled her to practice and prepare in a calm frame of mind.

Some Parting Thoughts

I won’t walk you through the other obvious stuff, like what makes a good presentation PowerPoint or how body language and appearance can improve your presentation skills—that stuff is what Google is for. You’re an expert by now at finding the information you need, so get out there and find it. However, know that if you need help getting ready for your defense, there are definitely humans around you (and some dogs) who want to help – whether that’s your chair, your family, or a coach like me. I recommend you find them now and let them tell you just how ready for this you are.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

• Avoid popular and eminent faculty member
• Choose the one you know very well and can approach whenever you need them
• A faculty member whom you can learn from is apt.
• Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Dissertation Defense?

1. Start Your Preparations Early

Thesis defense is not a 3 or 6 months’ exercise. Don’t wait until you have completed all your research objectives. Start your preparation well in advance, and make sure you know all the intricacies of your thesis and reasons to all the research experiments you conducted.

2. Attend Presentations by Other Candidates

Look out for open dissertation presentations at your university. In fact, you can attend open dissertation presentations at other universities too. Firstly, this will help you realize how thesis defense is not a scary process. Secondly, you will get the tricks and hacks on how other researchers are defending their thesis. Finally, you will understand why dissertation defense is necessary for the university, as well as the scientific community.

3. Take Enough Time to Prepare the Slides

Dissertation defense process harder than submitting your thesis well before the deadline. Ideally, you could start preparing the slides after finalizing your thesis. Spend more time in preparing the slides. Make sure you got the right data on the slides and rephrase your inferences, to create a logical flow to your presentation.

4. Structure the Presentation

Do not be haphazard in designing your presentation. Take time to create a good structured presentation. Furthermore, create high-quality slides which impresses the committee members. Make slides that hold your audience’s attention. Keep the presentation thorough and accurate, and use smart art to create better slides.

5. Practice Breathing Techniques

Watch a few TED talk videos and you will notice that speakers and orators are very fluent at their speech. In fact, you will not notice them taking a breath or falling short of breath. The only reason behind such effortless oratory skill is practice — practice in breathing technique.

Moreover, every speaker knows how to control their breath. Long and steady breaths are crucial. Pay attention to your breathing and slow it down. All you need I some practice prior to this moment.

6. Create an Impactful Introduction

The audience expects a lot from you. So your opening statement should enthrall the audience. Furthermore, your thesis should create an impact on the members; they should be thrilled by your thesis and the way you expose it.

The introduction answers most important questions, and most important of all “Is this presentation worth the time?” Therefore, it is important to make a good first impression , because the first few minutes sets the tone for your entire presentation.

7. Maintain Your Own List of Questions

While preparing for the presentation, make a note of all the questions that you ask yourself. Try to approach all the questions from a reader’s point of view. You could pretend like you do not know the topic and think of questions that could help you know the topic much better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussion will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After successfully preparing your slides and practicing, you could start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and relax if need be.

Pay attention to your body language. Stand with your back straight, but relax your shoulders. The correct posture will give you the feel of self-confidence. So, observe yourself in the mirror and pay attention to movements you make.

9. Give Mock Presentation

Giving a trial defense in advance is a good practice. The most important factor for the mock defense is its similarity to your real defense, so that you get the experience that prepares for the actual defense.

10. Learn How to Handle Mistakes

Everyone makes mistakes. However, it is important to carry on. Do not let the mistakes affect your thesis defense. Take a deep breath and move on to the next point.

11. Do Not Run Through the Presentation

If you are nervous, you would want to end the presentation as soon as possible. However, this situation will give rise to anxiety and you will speak too fast, skipping the essential details. Eventually, creating a fiasco of your dissertation defense .

12. Get Plenty of Rest

Out of the dissertation defense preparation points, this one is extremely important. Obviously, sleeping a day before your big event is hard, but you have to focus and go to bed early, with the clear intentions of getting the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise creates an immense impact on your self-confidence. All you have to do is visualize yourself giving a successful presentation each evening before going to sleep. Everyday till the day of your thesis defense, see yourself standing in front of the audience and going from one point to another.

This exercise takes a lot of commitment and persistence, but the results in the end are worth it. Visualization makes you see yourself doing the scary thing of defending your thesis.

If you have taken all these points into consideration, you are ready for your big day. You have worked relentlessly for your PhD degree , and you will definitely give your best in this final step.

How to Prepare for Your Dissertation Defense

4-minute read

• 1st August 2023

After years of research and study, you’ve finally reached the grand finale of your PhD years: your dissertation defense. Since defending your dissertation is the culmination of all your hard work, it’s essential to do everything you can to prepare for it.

In this post, we’ll take you through how to ready yourself for your dissertation defense so you can focus on your accomplishments and excel during this crucial professional moment.

What is a Dissertation Defense? 

The dissertation defense is the crowning moment of years of research – the final examination before a PhD student is awarded their doctoral degree.

During a dissertation defense, the student presents their research, methodology, findings, and conclusions to a committee of faculty members and experts in their field. The committee then engages in a question-and-answer session to assess the student’s understanding of the subject matter, the quality of their research, and their ability to defend their work under scrutiny.

Many PhD students consider it to be the defining moment of their academic career and their chance to prove their expertise in their chosen research field.

If all this sounds overwhelming – don’t worry. If you’re a PhD student, you’ll have plenty of time and opportunity to adequately prepare for your dissertation defense. Below are some strategies to help you get ready for this significant occasion in your career.

1.   Know the Requirements

Familiarize yourself with your institution’s guidelines and requirements for the defense process. Understanding the format, time limit, and expectations for the presentation will help you to prepare your material and anticipate any issues.

2.   Review Your Dissertation

Even if you think you know it inside and out, review your dissertation from beginning to end. It may have been some time since you’ve last read and considered certain portions of your research and findings. Consider what your committee might ask about your research questions , data analysis, and conclusions.

3.   Work on Starting Strong

To begin your defense on a strong note, work on creating a clear and engaging introduction. You can start by briefly outlining the purpose of your study, research questions, and methodology . Try to stay on topic and don’t veer off track by discussing unrelated or unnecessary information.

4.   Practice Presenting

Practice your presentation skills by rehearsing your defense multiple times. Focus on clarity and pacing and try to stay within the allotted time limit. It also helps to record yourself so that you can see yourself from your audience’s point of view.

5.   Practice Q&A Sessions

To build your confidence, enlist friends and colleagues to conduct mock question-and-answer sessions. When practicing, remember to pause before answering questions you’re unsure of. It’s better to take your time delivering a response than it is to give an inaccurate or incorrect answer.

6.   Seek Feedback

Find out if your institution offers mock defense sessions where peers or mentors play the role of the committee, ask you questions, and give feedback . You can also have colleagues, mentors, or advisors review your presentation and offer practical feedback.

7.   Create Visual Aids

Think about any visual aids , such as slides, you may want to use to illustrate your defense and prepare them in advance. Be sure to check that your university allows visuals or images and that they enhance, rather than overwhelm, your presentation.

8.   Stay Calm and Confident

It’s natural to feel nervous but try to stay calm and composed during your defense. Take deep breaths and remind yourself of the expertise you’ve gained through the experience of writing your dissertation.

November 30th, 2021, defending a phd thesis is an emotional moment candidates and supervisors should be prepared for.

4 comments | 55 shares

Estimated reading time: 6 minutes

The PhD defence, or viva, is significant academic rite of passage, which as well as marking the culmination of years of study, can also be a highly charged emotional moment.   Drawing on years of collecting accounts of PhD defences on her blog and her recent book (Planning and Passing Your PhD Defence, co-authored with Olga Degtyareva),  Eva Lantsoght , discusses how both PhD students and supervisors can benefit from a more engaged understanding of the emotions underlying the PhD defence. 

In the days leading up to my doctoral defence, I had a recurring nightmare about my supervisor forgetting to show up for my defence. I was well-prepared, and since I was defending in the Netherlands, my thesis was already printed and approved. Failing was virtually impossible. Why then, was I nervous about my doctoral defence to the point of having recurring nightmares?

After eventually passing my doctoral defence, I decided to collect stories about the doctoral defence (or viva, depending on the country) around the world for my blog. I was originally fascinated by the differences between defence formats (such as the sword newly minted doctors receive in Finland and the medal in Chile ). Over time, however, I started to see that below the superficial differences, all types of defence show similarities. One is that there is always an emotional dimension to the defence. My worries before my defence were hardly an isolated case. Many doctoral candidates report strong emotions around thesis submission, in the weeks leading up to the defence, during the event, and even afterwards, when the post-defence blues may kick in.

Typically, discussions on the doctoral defence centre around the scholarly dimension. A defence is often viewed solely as an academic event marking and evaluating the end of a research project

Typically, discussions on the doctoral defence centre around the scholarly dimension. A defence is often viewed solely as an academic event marking and evaluating the end of a research project. However, in our recent book Planning and Passing Your PhD Defence , which I co-wrote with Olga Degtyareva, we have paid special attention to the emotional dimension of the defence (of course, in addition to the scholarly dimension preparing for answering questions, and other traditional aspects related to the doctoral defence). This was in part because, we strongly felt that we shouldn’t consider the defence as a regular examination, where a standard set of criteria are used to assess a student. Besides its function as an examination, the defence is also a rite of passage, a confirmation, a celebration, and the culmination of years of independent research work. Emotions are murky and difficult to factor in for assessment. The emotions involved in the doctoral defence make it a unique event: for the candidate, the examiners (or committee members), and for the supervisor. Being aware of these emotions, and bringing them to light, is important to understanding the defence better and the role it plays in a research career.

In my work on the doctoral defence, I found (to my surprise) that the major differences between defence formats did not influence the candidates’ perception much . On the other hand, I did find important differences in the emotions felt by candidates related to the defence, as a function of socio-demographic aspects, notably gender. Women doctoral candidates experience more negative feelings before the defence, and if they had a negative experience during the defence, the negative impact on their perception as a researcher could often be long-lasting. Being aware of how different groups experience the emotions related to the defence differently is important, especially for supervisors and examiners, and can be empowering for candidates. Besides simply being aware of the emotional dimension, it can also enable the small changes that can help settle things when emotions run high: taking a short break, offering water, getting up to open a window, or moving to another topic of the thesis.

While each PhD candidate, each research study, and each PhD trajectory are unique, there are some common emotions that deserve to be mentioned. First of all, in the weeks or days leading up to thesis submission, candidates often feel that the work is not enough, worthless, or otherwise insufficient, and these feelings can contribute to perfectionism. Other candidates may be so tired of the thesis that every small action may feel like a terrible chore. Some feel relieved upon submission, and others worry about how it will be received.

Many candidates also worry about how they will perform. For candidates in the United Kingdom, where the viva takes place before final submission of the thesis and may determine the level of corrections required for the thesis, candidates worry about what the outcome of the thesis and viva will be. Major revisions could potentially add months to the doctoral journey. Because the viva is behind closed doors, candidates also may not know very well what to expect. In the Netherlands, where candidates are sure they will pass, other causes lead to worry and anxiety. As the defence is public, candidates feel the pressure to perform well in front of the committee, friends, colleagues, and family.

it is also important for supervisors and examiners to be aware of this emotional dimension, and to know how different groups of candidates experience these emotions

The first step in dealing with this anxiety, is to name and acknowledge it, and to know that these feelings are normal. Candidates who passed without corrections worry about passing their defence as much as those who had more work on their thesis after the defence. Breathing techniques, meditation, and relaxation exercises can help. University counselling services should be there to support as well. Being well-prepared for the day of the defence itself may also help candidates to feel more in control over the day and their feelings. A positive action, such as stopping by colleagues and expressing gratitude to them before the defence, can improve defence-day-anxiety. Many candidates feel more nervous right before and at the beginning of their defence. Taking notes, repeating the question, or asking for clarification of the question, are all valid options to start answering in a calm and controlled manner. At the end of the defence, candidates can be nervous to hear the outcome, and the minutes while the committee is in deliberation may feel like hours. Then, after hearing the verdict, often the final flood of emotions (relief, happiness, pride, or perhaps disappointment, anger, or worry about the thesis revision) comes.

Emotions play an important role leading up to and during the doctoral defence. Understanding the role of these emotions is important for candidates, so that they know that what they are feeling is normal, and does not mean that they are not worthy of a doctorate. At the same time, it is also important for supervisors and examiners to be aware of this emotional dimension, and to know how different groups of candidates experience these emotions. Being aware of and holding space for these emotions allows all those who are involved in the defence to experience the defence, not simply as a test of knowledge, but as the important moment it is, in the formation and affirmation of a new scholar.

• 10 Ways To Successfully Defend Your PhD

First, what does it take to give a successful PhD Defense? How can you prepare, keep the stress levels low, and make sure you have the highest chance of success?

I’ll just say that everyone’s PhD Defense is unique and is unpredictable. Your talk/presentation is only as good as you want it to be. And you cannot fully prepare for all the endless possibility of questions. If you wrote a 200 page thesis, your thesis commitee can pick apart an error bar on a graph on page 133. They can ask you what you meant by a word in a random sentence in any given paragraph. Keep in mind, this is all just apart of the PhD hazing process, and in a sense is just to humble you. At the end of the day, if you wrote a good quality thesis and are CONFIDENT, you should have no problem successfully defending and leaving that room with a sense of relief. Either way, I wanted to share my experience while it is still fresh in my mind

1) Do not underestimate how long it takes to prepare your slides/talk and make sure you give multiple practice talks

When I turned in my thesis two weeks ahead of time to my committee, I thought the hard part was over. Although a very important milestone, don’t let your guard down. If you already have most your slides ready to go, then you are lucky. I ended up getting data at the last minute and my story changed. I had to make many model slides from scratch.

If you want to give a GOOD thesis talk, you need to practice multiple times . And this means that you don’t cram it all in a couple of days right before your talk. I’m not talking about giving just one practice talk. You need to give multiple group practice talks. In between, you need to practice on your own.

You certainly don’t have to memorize every word of your thesis defense talk, but you should have it well-polished. There is no limit (or requirement) on how many practice talks you should give, but give as many talks as it takes until you feel like you are ready. If you are unsure of the quality of your talk (or being “ready”), tape record yourself or watch a video of yourself to see just how good it is. You might be surprised when you play it back to yourself.

You should also time your talk. I noticed that I tend to talk faster (by about 5 minutes) when giving the actual public talk vs. when I practice on my own. The length of the talk can depend on many departmental factors. My talk was ~45-50 minutes long which also leaves time for questions.

Either way, do not procrastinate on your slides and/or talk until days before. Make sure you use the full two weeks to perfect your slides, polish your talk (and be very concise about your words), and review material you are unsure about.

2) Listen to other thesis defense talks

The best way to mentally prepare for your thesis defense talk is to listen to other thesis defense talks. I actually went and got a few talks on DVD (the good ones that I remembered). If their research is on a similar topic as your own, this would be more ideal-but take what you can get. When you watch the talk, ask yourself what makes it good or bad? Were they enthusiastic and sincere? Did they keep the energy throughout the talk? Were there some rough areas of the talk? When nerves are running high, talks may not go as expected. You can battle this nervousness by showing up well-prepared. If you are, the thesis defense talk is just a formality.

If you cannot obtain any thesis defense talks on video, make sure that you go to actual public thesis defense talks. At least go to one so that you have a good idea of how to TIE the whole story together and give your audience the big picture. Keep in mind that you are giving a talk to a general audience . This means that use of jargon and highly technical terms will only put your audience to sleep. Make sure it is clear and understandable. Simplify it the best that you can and put it in the larger context of your research field. Use cartoons or model slides (if necessary) to give your audience the general, overall picture.

3) Have your friends, labmates, and others drill you with questions

What’s the best way to prepare for unforeseen questions? Have others that are familiar with your work drill you with questions. Chances are that even though these questions may not be the actual questions you will be asked either by the public and/or your thesis committee, it prepares you to think on your feet. It also builds your confidence . And the questions that your labmates or friends ask you may just be the same question you will get asked on your defense day.

4) Re-read over your entire thesis and write out your own list of questions

You may be sick of reading your entire thesis over and over by now, but you need to keep everything fresh in your mind. I actually read over my entire thesis multiple times during my final two weeks and came up with my own list of questions that I thought my committee would ask me. In addition, I also came up with a list of questions that I had of my own (questions that I was unsure of or that I thought were a weakness of mine). If you cannot come up with a list of good questions, then you are not trying hard enough.

Even though my committee didn’t ask me my exact list of questions, the process of  coming up with my own list of questions-then finding the answers to those questions (beyond my thesis)-actually helped me gained a deeper understanding of my project. And it was a confidence booster in disguise.

5) Don’t let distractions get to you

Completing your thesis is a huge milestone. Those last two weeks until defense day can be stressful. Whether you are doing job interviews, applying to other jobs, or you want to “jump the gun” and finally start your post-PhD life, don’t give into temptation. Keep your guard up until your actual defense day. This is key to giving a good talk. You need to go in with the mindset that you will kill your presentation and give a long lasting impression to your audience. I have actually heard that some people who gave great thesis defense talks were offered a position shortly after (i.e. a postdoc).

You are going to want to do all those little tasks that you have been putting off for so long because you have spent X amount of months writing your thesis in solitude and you had no time to do them. Your list could be very long. I can tell you that one of the things on my list was to keep publishing blog articles and keep my blog running. I simply did not have enough time. Prioritize and focus on your defense talk and nothing else . If you are looking for jobs during this time period, I will be writing about this in Part 3 of this series.

6) Get plenty of sleep, keep your diet in check, and take care of yourself

This might be the most difficult thing for anyone. I struggled with this the most while writing my thesis. Skipping meals, late nights, overloading your system with caffeine just to stay awake. You have to fight it the best that you can. A month before my defense talk, I hit the gym 3x a week (for the first time in months). Everyone handles the anxiety of their defense talk differently. I am someone who thinks about it constantly. So it becomes hard to focus on other things, like taking care of yourself.

Once your thesis is turned in to your committee members, during those final two weeks- sleep and a proper diet are KEY. The day of your defense, make sure you are well-rested (don’t stay up all night stressing about it) and eat well. Don’t sell yourself short. By taking care of yourself, you ensure that you have the highest probability for giving a great thesis defense talk and showing your committee members that you are confident about your project.

7) Keep your cool and relax

When your defense day comes, you have to remember that you have put in a lot of HARD WORK to get to this point. You know your topic better than anyone . Because of this, you have no reason to be stressed out.

When your committee pushes you and asks you questions, they again will push you to your limits. You will meet a point where you won’t know the answer. Also, a question could simply be a future direction/experiment that you simply haven’t tested yet. Remember that they are simply trying to test your knowledge and humble you. You don’t have to know all the answers. Therefore, when you are answering questions, keep your cool and relax. Answer the questions the best that you can and you should have no problem passing. And in all honesty, the prelim (or qualifying exam) was much harder than the actual defense…

8) Don’t focus on the after-party until you have actually reached the after-party

Who doesn’t want to spend their final two weeks planning the celebration? Although I did have an after-party, I did not go to great efforts to plan it like a wedding party. As I said in #5, prioritize and focus on your thesis defense talk and nothing else. Plan your after-party while you are on break from your practice talk/preparing for questions/working on slides but do not make it a number one priority. Once you have passed, then you can change your focus. The feeling is indescribable (see #10).

9) Have a good structure

A good thesis talk also has a good introduction before going on to the next idea or slide. It should flow in a logical manner and be smooth. That is why #1 is important, because many people don’t spend enough time in the creation of good powerpoint slides. Your slides and talk have to MATCH up , meaning you can’t have really good slides and a mediocre talk (or vice versa) if you want it to go well.

This is why practice is important, and if you spend enough time on BOTH the talk/slides you will give a very good talk. A lot of times while I was actually practicing my talk, I had to go back and change the order/wording of slides or how I introduced certain slides (the wording) so that the flow would be better.

Be formal in how you word things (i.e. say “our data show that”… vs. “you see here that”…). To give a good introduction, it might be wise to use slides that ask a question in between. This question slide (break) in-between your next idea allows for your general audience to CATCH UP and understand your logic . Why are you doing this experiment? If you just show a bunch of your published data with no introduction (and maybe a title that gives an interpretation/punchline), you will overwhelm and bore your audience.

Many scientists forget that although they are an expert on their topic, what seems easy and understandable to them-does not apply to others outside of their field .

Before you go to your next data slides introduce the idea (based on this data I wanted to ask this question). Then tell them WHY you performed this particular experiment (which is basically in the form of a question). Once your audience understands why, go on to the next slide and give them your interpretation. In other words, don’t just jump to the interpretation . This will keep your audience’s attention and make sure that your thesis defense talk gets a lot of positive feedback and leaves a good impression on your committee members (it really does show).

10) Visualize yourself giving your defense each day and think about how good it will feel when it’s over

This one is pretty self explanatory. I will say that when it is all said and done, it feels like a huge burden has been lifted off your shoulders. It is emotional and you finally feel that all that hard work and time that you put in over the years-was all worth it in the end. Good luck to all those who are preparing for their defense talk in the future! Think about what it will be like to get up in front of a large audience and show everyone how you moved a field forward. This is YOUR moment to show everyone you are an expert in your field. The more you keep this mentality, the better your talk will be. Keep your cool and relax (#7) and everything will be fine.

Best of luck to all!

My PhD defense is next week and I am having negative thoughts about my work and knowledge. Any advice on how to tackle this?

I am presenting my PhD thesis in front of my committee next week and I feel that I have just not done enough. My work is simple and I also feel that I have poor theoretical foundations and am going to be an embarrassment when quizzed by my committee.

I am not feeling confident about presenting my research and I am finding it extremely difficult pushing away negative thoughts like (I feel I have not done enough or I am not theoretically strong enough for doing my PhD on my research field).

I am revising theoretical stuff (related to my thesis work) that I studied in my first year of PhD, but I am not able to push out the feeling of guilt and the impending doom.

Any advice on how to tackle this?

Take a deep breath. You will be OK. You're suffering from impostor syndrome .

PhD defenses are traditional formalities. Your advisor wouldn't let you schedule yours if they didn't think you ready.

The examiners are more likely to want to know what you did than theory from your first year you have forgotten.

When you pass your defense come back here and tell us about it.

• 28 While I generally agree with this, the third paragraph may be true or not. There are places where the defense is actually an important and thorough examination. But if that is the case, the OP should know that already. –  Buffy Commented Nov 17, 2019 at 15:33
• 4 Academia varies more than you think –  gerrit Commented Nov 18, 2019 at 9:26
• 9 Not everyone suffers from impostor syndrome. It's not paranoia if they're actually out to get you. It may also be the case that OP is genuinely underperforming and that they are rightly concerned that they are actually unprepared. We don't have the information to make that determination. –  J... Commented Nov 18, 2019 at 15:18
• 3 Well, your first three sentences sound like a firm diagnosis. It's a supposition, at best. –  J... Commented Nov 18, 2019 at 15:33
• 3 @J... at least with the way it works in the systems I'm familiar with, their supervisor clearing them to defend their thesis is fairly strong evidence that they should be capable of doing so –  llama Commented Nov 18, 2019 at 17:29

Here's the thing: People's dissertation work is usually not an earth-shattering achievement.

I feel that I have just not done enough.

I feel my Ph.D. was sorta-kinda enough; and a "strict version of me" might not have accepted it.

(in hindsight I developed a better opinion of it. I now feel it was solid enough work.)

My work is simple and I also feel that I have poor theoretical foundations

Well, your work may be simple (or it may not), but most research findings are simple once you have all the context in mind. The point is that you discovered or invented something new that wasn't known / didn't exist before. You have done that; and that's basically why you deserve your Ph.D.

As for the lack of theoretical foundations - ugh, tell me about it! Even at my peak I felt like an empty-headed fool compared to the "sages" of my field. Again, it's possible that you're under-estimating yourself, but it's also possible that you're setting unreasonable expectations: Most Ph.D.s in your field know less than you do about what you've been studying.

and am going to be an embarrassment when quizzed by my committee.

From best to worst:

• You'll probably know enough about what they ask you to say something non-embarrassing.
• "Esteemed opponent, that is an interesting idea. I have not considered that avenue during my doctoral work, and would need some time to consider it. It may well lead to further results beyond my own work."
• "Esteemed opponent, I am not versed in [insert complicated subject here]. It is possible this field may have bearing on my findings."

Now, is no. 3 embarrassing? Well, it might be. But it's also the truth. Don't try to run from it in your head. You know what you know, you've done what you've done, you are who you are. That's not shameful.

I am not feeling confident about presenting my research

You should present what you did. Don't try to glorify it, nor to downplay it. What the question/goal/challenge was, how you approached it, how/why it worked, what the results were, what the consequences/corollaries/implications are. You can be "confident" about that - since these are just facts.

I am not theoretically strong enough for doing my PhD on my research field

You are strong enough in the sense that you've already done your Ph.D. work. You're not auditioning for the title of all-knowledgeable theorist.

I am not able to push out the feeling of guilt and the impending doom. Any advice on how to tackle this?

As for the guilt - don't try to make it disappear. Just try to separate the presentation from the guilt. You present the stuff that you're not guilty about.

As for the sense of doom - I tried to make the non-doom'ishness more palpable for you; I hope this works.

• 3 To further reduce the feeling of doom, let me point out that, even though this event is called a "defense" everywhere (as far as I know), the examiners are called "opponents" only in some places --- not, for example, in the U.S. –  Andreas Blass Commented Nov 18, 2019 at 0:56
• 1 "Most Ph.D.s in your field know less than you do about what you've been studying." This is basically the definition of a Ph.D. In the course of doing the research, the candidate is becoming the world's foremost authority on that particular topic. –  John R. Strohm Commented Nov 18, 2019 at 22:08
• @AndreasBlass: TBH I think it's fair that it should be a defense, that the opponents be opponents, and that they make an fair attempt to question the candidate's research findings if they have weak points etc. This may be less psychologically convenient for the candidate, but it is in the interest of science. –  einpoklum Commented Feb 21, 2020 at 17:26
• @einpoklum When I'm an examiner, I'll look for weaknesses in the thesis, but if I find any, I won't wait until the defense to ask questions. I'll ask the candidate or the adviser beforehand, to give an opportunity to correct the problem. Only if they can't or won't do that, or if the problem becomes visible only during the defense, would I act as a genuine opponent at the defense. –  Andreas Blass Commented Feb 21, 2020 at 17:33
• @AndreasBlass: I don't think the two contradict. I would basically do the same, except that I would be oppositional during the exam and expect the candidate to have addressed the issue I had pre-informed him/her about. –  einpoklum Commented Feb 21, 2020 at 18:32

I like the given answers but I'm surprised there isn't more practical advice in them. If you want "things to do", here you go:

As someone who recently defended (successfully) and felt similarly before the defense, I think you are not only suffering from impostor syndrome, but a separate feeling that probably has/deserves its own name.

As the creator and person most familiar with your own work, you are more aware of its faults than anyone else in the world.

There is a lot of good advice here about trusting the process and your advisor's opinion about your work, but I'll offer some other practical tips for dealing with your anxieties that only you can understand, because only you are fully familiar with your own work.

• Preparation helps quell anxiety : Practice your talk, with your advisor if possible. Try to come up with the questions that you would be most afraid to answer. Then come up with some imperfect answers to said questions. At this stage, remember that it's expected to have limitations in your current work . Nobody can expect you to have done everything, so making simplifying assumptions, leaving things for future work, etc are almost always acceptable answers. This is what people mean by "trusting the process." They mean that if these sort of terrifying questions actually uncovered fundamental flaws in your work, then your advisor should have found them much earlier. I would argue that it is most important simply to show that you have put some thought into these "scary" questions.
• Don't sell yourself short : Even if you don't know exactly how to do something. Be clear up front about the limitations of your work, but don't frame those limitations in terms of your own personal abilities. If you are asked a question you can't answer totally, get as far as you can. Say "while we have strong intuition (for x,y,z reasons) that there exists theory to back up our empirical results, we leave that derivation to future work. We might derive it by trying Q, R, and S on problem formulation T". Don't say "I don't know how to derive this so I didn't, and I have no ideas for how I might do it".
• Fake it 'til you make it : My advisor gave me some really nice advice before my defense: part of the committee's goal, whether they mean to or not, is to determine whether or not you seem like you should be given the same Ph.D. title that they have. You are being inducted into a community. So act like a humble but full-blown researcher. When they ask a question, they often don't have a correct answer in mind: they're probably legitimately trying to gain an insight from another expert (you) who has done work related to theirs. When someone makes a suggestion/critique that you haven't thought of, take a moment and weigh its merits. If you have doubts, explain why. Ask them to clarify. If you think it makes sense, don't be hard on yourself and say "I should have thought of that", say "Oooh interesting, we tried the approach we did for X,Y reasons, but we should follow up on that in future work. Maybe your approach lets you do BLANK". If you can, draw on previous experiences of attending technical talks given by strong researchers for this. If you can't remember any interchanges, youtube has plenty of examples.
• Invest in good pizza : No, I'm not being facetious. At the end of the day, these are humans judging you, not machines (as of November 2019). Human judges are invariably subject to all sorts of confounding variables when making judgements. For example, studies have shown correlations between judge leniency in criminal trials and the time of the day: you're more likely to go to jail when a judge is hungry (i.e before lunchtime). If you are able, supply your audience with good food at the beginning of your talk. If that doesn't work, at least you'll have good food to eat after a bad experience! At the very least ensure that your committee has access to pens, paper, water, and the comfiest chairs in the room. I was asked zero hard questions at my defense, even though I could think of quite a few, which I partly attribute to the local pizza place.

Hope that helps, best of luck!

• #3 is so important, and it's perfectly legitimate for "X,Y reasons" to include things like "that's all we had time and money for". –  G_B Commented Nov 20, 2019 at 1:06
• Mostly good advice. I don't think buying pizza for the committee is a good idea. I wouldn't quite call it bribery, but it is a little tacky. –  Ethan Bolker Commented Nov 20, 2019 at 18:04

Let me emphasize the "trust your supervisor" advice that others have already given you. I don't know the official procedures in your department, but I imagine they're somewhat similar to those in my department. Before one of my Ph.D. students can schedule a thesis defense, I have to provide two official documents. One is a description (usually about two pages long) of the work in the thesis, ending with my recommendation to my department that the thesis be accepted. The other is not for the department but for the graduate school; it doesn't require as much information about the thesis, just some general comments on its quality, but it must also include my statement that the thesis is acceptable (perhaps with minor revisions). Furthermore, a second faculty member must provide an independent evaluation for the department, and all members of the committee must provide the second form for the graduate school.

So, by the time of the defense, I've already officially stated (twice) that this thesis is worthy of a Ph.D. I wouldn't do that if I wasn't confident that the student can pass the defense. If anything went wrong at the defense, I'd be at least as embarrassed as the student.

• It is possible to submit a PhD without the approval of the supervisor at some universities. Of course, to do so implies a massive falling-out with the supervisor. –  Martin Bonner supports Monica Commented Nov 19, 2019 at 13:31
• In my department, although candidate don't technically need their adviser's approval, they do need the approval of the department's doctoral committee and of the graduate school administration. If neither of the two reports for the department is from the adviser, the doctoral committee will surely investigate the reasons for that situation. In effect, this would amount to the student's getting a new adviser. –  Andreas Blass Commented Feb 21, 2020 at 17:37

To complement what @Ethan wrote, trust the process.

No (good) supervisor will let you do irrelevant work and defend insufficient results. If you have good supervision, trust your supervisor. By the point of defending you should have at least a few peer-reviewed papers and conference presentations under your belt. Use that to convince yourself that your results are relevant.

You can always do more, however that is not the point of Ph.D. The point is to learn and demonstrate knowledge of how to do research.

Even if your results are insufficient and you are facing the committee as a means of evaluating your work. The committee will point out specific deficiencies in your work. Their feedback is for both you and your supervisor to consider and adjust the course.

Do not assign your self worth to the thesis work. There is more in life than just that!

My supervisor mentioned 3 key points that were checking in the viva.

Interesting work

The work is correct

You did the work

You have done the work. Understand your own work first, not stuff related to your thesis. Trust your supervisor on the first two.

I have never seen anyone not nervous before a viva. My other half commented that I still had some shakes when we went for lunch an hour after my own (and that was a good result).

And then the final thought is that in most countries it is very hard to shift grade very far in a viva. It is on the thesis which has already gone. Finally issues happen and mistakes happen in a thesis. Minor corrections are generally to be expected and major ones happen. If either result comes in it is still fine. Take the notes on board and fix the issues pointed out, no different to a paper review (albeit normally a bit more work).

You should feel proud getting this far. I know plenty who didn't.

• Grades? In the UK, a PhD is a simple "pass/fail" (well, actually the viva result can be "rejected", "passed with minor corrections", and "passed" - and most are the middle). There is no concept of a "good grade" –  Martin Bonner supports Monica Commented Nov 19, 2019 at 13:53
• Yeah I meant pass without corrections/ pass with minor corrections / major corrections (essentially a large scale rewrite and resubmission, generally taking months to do) and rejected as the 4 "grades". Most are minor corrections alright. They are not quite traditional grades but I tended to consider them as such. –  Christy Commented Nov 19, 2019 at 14:15
• Ah right! (I'd forgotten "major corrections"). –  Martin Bonner supports Monica Commented Nov 19, 2019 at 14:20

The fact that you have submitted your thesis is in itself an achievement, with sufficient responsibility shared by your Guide too. You may have already worked out and specified some propositions in your submission. You need to list them during the ViVa and explain them, to provide more clarity during your presentation. Always try to present objectives clearly and refer to them sequentially, while highlighting the conclusions of the study. Also, mention some of the obvious limitations and explain (if possible) as to why they happened and how the next study on your topic can get over them. Finally, this is only a defence of what you have done. So, believe in it and go forth and defend. All the best!

You feel ashamed by your work ? Please don't ! A lot has been said by other contributors, but I would go further, make one more step.

You probably think about all what you have NOT done during your PhD and it's normal, you can not explore all the possibilities. for the quiz with the jury members, feel open. It's not a lawsuit, it's a discussion between people who are relevant, passionate and know a lot about your PhD issue. It's a great (and maybe the only one) opportunity to have the most relevant advice and ideas on your work.

As far as I'm concerned, I really enjoy the quiz part, even if I were petrified at the very beginning of my presentation. I understand that jury's members are not there to judge you, but to put the introspection to a next step. I realize I miss some opportunities during these years of tough work, but more essentially, I understand that I need to share more my work and discuss with people more often, even if everything is going well. It should have opened more doors and now, I'm aware of that.

Your presentation is just one step in your life and you are prepared for that. It's like a wedding ceremony, lot of pressure but it will past too quickly :) You know a lot about your topic, just relax, be open to conflicting views, stay in a productive state of mind and you will enjoy it.

Identifying your problem as being " imposter syndrome " is, I think, correct. The greater problem is to find a way of overcoming it. Negative thoughts are not easily dismissed and repeating to yourself that your work is OK and that there is no need to worry is, of itself, unlikely to be sufficient.

A strategy that I have found useful in similar situations is to imagine myself as a legal advocate for a client. It's a job , it's not personal. I'm not here to evaluate the client. My job is to be the very best advocate for them that I can be. Afterwards, when "we" are celebrating our success, I can tell the client I didn't believe a word of it (insert wry smile here).

There is so much fake research going on under the guise of PhD. It has become just like any other Masters defence. No one cares much about the results, no one is gonna check/review them. You are gonna do just fine my friend..... just go in there with a wide smile, and say everything you have done very confidently. You are gonna do amazing :-).

Also, you have worked really hard for 2/3 years now and your examiners will take that into consideration. Also consider the fact the you are gonna be part of the top 1 percent in the world. Its a really huuuuge achievement. So just go in there, and kill it with whatever you got.

Been through that for my PhD and did very well, your anxiety is normal. Prepare a very good and detailed defense presentation: I suggest you organise it as follows: (list from my PhD supervisor Veronica Orvalho)

• Problem statement, very short and clear
• teaser video of what you have done that supports the problem statement you previously defined
• Explain the problem
• Explain the objectives of the thesis
• overview of the solution
• Explain core of the thesis
• Contributions (include papers, patents if you got any, awards...)
• The future after your thesis, how your work can impact other areas of research or open new areas of research. Best wishes!

I did a PhD defense as well, in 1984. Hard core physical science. Getting this far, it's highly doubtful you could fail at this point, and hopefully your committee knows that. More importantly, just be confident, mainly because you probably know more than anyone else on earth about your thesis content and subject. Good luck, it will go fine.

How to Successfully Defend Your Dissertation & Not Have a Nervous Breakdown

Today marks the 1 year anniversary of my (successful) dissertation defense. Even though things obviously worked out in my favor, that still doesn’t take away from the empathy I feel while I watch my colleagues go through this arduous process. I remember very little from the two months leading up to my defense. It’s pretty much a blur. By the time the day actually arrived, I was exhausted, exhilarated, and everything in between. I didn’t know what to feel. Others wanted me to be excited that I was “finished” (for those of you Ph.D.’s out there, you know that the defense is only one, albeit major, benchmark to graduation) while my committee members made seemingly joking remarks about “now the real work begins”. I think I felt my soul die a little bit. In preparation, I remember spending time with Google asking questions like, “tips for a successful dissertation defense”, “how to not cry in the middle of your defense” (lol), “dissertation defense examples”. While some of the information I found on the internet was helpful, I don’t really feel like anything I read really prepared me for that experience. I put together a list of tips based on my own experience and that of my colleagues, and hopefully you find some (or all) of this helpful!

Learn by watching

Sit in on other defenses. This is the best way to get an idea for the environment, content and vibe of a dissertation defense. I mean, let’s be honest we all would rather learn from other people’s mistakes than make our own. I sat in on a handful of defenses before I gave mine, and I really think it made a difference in my plan of attack. I also picked the brains of my more senior colleagues about things they wished they would have done differently. Sitting in is also a collegial act that helps build connection with other academics.

Practice makes perfect

True in most areas of life, and exceptionally true in the case of dissertation defenses (& any presentation, really). I practiced my defense so many times that I was rehearsing it in my dreams (no joke). Given that most defenses have a time limitation, practicing is essential, especially if you tend to go off on tangents. You shouldn’t be dependent on your presentation slides. A good presentor has a conversation with their audience where the slides simply serve as a roadmap for that conversation. I like to think about the advice I got from a mentor of mine who said, “Know your defense well enough that if the power went out you could keep going.” This is advice that I have carried with me into my professional life.

Suck it up & get feedback

I tend to be hyper self-critical. It sometimes impacts my desire for feedback even though I know how valuable constructive criticism can be. I can let the fear of someone criticizing my work inhibit my professional development and ultimately producing a higher quality product. So, how did I overcome this hurdle? I gave my defense slides to a couple people I felt completely comfortable with – close friends, close colleagues. It’s advantagous to get feedback from both academics and non-academics. A variety of lenses will help you view your presentation in many shades – some of which may be immensely helpful and bring new insight into your work.

Let off some steam

For those of you who are part of #BachelorNation, take a tip from Corinne Olympios and take a nap, I mean hey, “Michael Jordan took naps. Abraham Lincoln took naps.” My point is, do something that helps you relax and center yourself (something that is a good habit to develop, in general). When I’m super stressed out I take to one of two activities (sometimes both): cleaning & running. I think I’m drawn to both of these activities because they’re physical and upon completion give me a sense of accomplishment. Play “Shake it Off” and dance around a bit (totally done that before). Get on Instagram and browse photos under #puppy – there’s research to support that looking at cute things can have positive health impacts like adding 7.5 minutes (see here ) on to your life and lowering your blood pressure. You do you.

Confidence is key, so don’t bullshit

You need to know your defense presentation backwards and forwards (see “practice makes perfect”). Don’t try to bullshit your way through your results section. I know in my field this tends to be the most complex area. You need to know why you chose your analysis plan, how to explain it and how to make inferences from it. Think of your defense as a multi-course meal. This is the main course of your presentation, and it’s the longest course of the entire meal. If all of a sudden your meal went from salad to desert you would be wondering why, and so will your committee. Knowledge is power here.

Plan a post-defense reward

I had a bottle of champagne in my fridge for two months with a tag that said “Do not drink until after defense”. It was a solid motivator during that last week when all I kept thinking about was how once I was finished I could come home, pop that champagne, and celebrate this amazing accomplishment. Find something to reward yourself with that can help keep you motivated – a trip, that cute dress you’ve been eyeballing, a night out with friends, or in my case, a bottle of champagne. Celebrate! You deserve it, Dr.!

Here are a few tips for the day of :

• Don’t have too much caffeine. You’re already going to be hyped up and pumped full of adrenaline. Have your normal morning cup of coffee/tea and then cut yourself off.
• Try to schedule your defense earlier in the day (you don’t want to be waiting around all day).
• Dress to impress. Research shows that if you feel confident in what you are wearing that you are more likely to perform better in a task. Rock that #bosslady/#bossman outfit.
• Get there early. You do not want to be rushing. Worse. feeling. ever.
• Invite some friendly faces. You’ll want to have some people you can trust in the audience that will nod enthusiastically while you’re talking about your research.

What other tips and tricks do you have to help get through stressful academic moments like this? Comment below?

WORK WITH ME

Thank you for sharing your tips and experience. I will be defending in a matter of weeks. I fully understand the varied emotions and feelings that you talked about. I am looking forward to completing this MAJOR milestone.

Wow – congratulations! This is a huge accomplishment. Going through this process, is just that – a process. You will be processing all those emotions as you continue to prep and then afterwards. Just remember that, assuming you prepared the way you’re supposed to, you are the expert on your topic the day you present. Go into it with confidence! I wish you all the best the day of!

Defend A Thesis: Prepare For Your Thesis Defense For PhD

When you’re nearing the end of your graduate program, a critical milestone looms: the thesis defense. This isn’t just a formality; it’s your chance to showcase the depth of your research and knowledge. 

In this post, we explore what is a thesis defense, the process, and how you can do well in it. 

What Is A Thesis Defense?

A thesis defense is a crucial component of completing a graduate degree, where a student presents their research findings to a panel of experts, typically comprising faculty members from their university.

This event marks the culmination of a student’s research efforts and is a formal requirement for obtaining a master’s or PhD degree.

A thesis defense is also quite similar to a dissertation defense. Both involves a student presenting their research to a panel of experts and answering in-depth questions.

The main difference typically lies in the level of study—thesis defenses are common in master’s programs, while dissertation defenses are associated with doctoral studies. Both assess the student’s research rigor and depth of knowledge.

A thesis defense is usually a nerve wrecking experience for many PhD students, but with the right knowledge and preparation, it is usually managable.

Why Must a PhD Student Defend Their Thesis / Dissertation?

There may be doctorate programs that does not require thesis defense, but PhDs generally need to do this. There are several reasons why PhD students must defend their thesis:

Demonstration of Expertise

A thesis defense compels you to consolidate your research into a coherent presentation, showcasing your depth of knowledge and critical thinking skills.

During this oral examination, you answer open-ended questions posed by a committee of faculty members. This is your chance to demonstrate that you are an expert in your field, having moved from a student to a scholar.

Mastery of Subject Matter

The defense process requires that you not only know your study’s details but also how your work fits into the broader field.

Committee members, including your advisor and other professors, will probe your understanding, asking you to justify your methodologies and conclusions.

This is akin to a rigorous job interview where your task is to convince them of your thesis’s merit.

Feedback Opportunity

This is a rare moment to receive direct, critical feedback from multiple seasoned academics. Their insights can profoundly shape the final version of your dissertation, refining your arguments and possibly influencing future research directions.

Engaging with their questions helps you think more deeply and respond to critiques that you might face when publishing your work.

Validation of Research Efforts

Defending your thesis validates your years of hard work. Successfully articulating your research process and findings in front of the defense committee is a significant accomplishment in itself.

It’s a formal acknowledgment by the academic community that your research contributes valuable knowledge and meets the rigorous standards required for a graduate degree.

Professional Preparation

The skills you hone while preparing for your defense are invaluable in any professional context, including:

• articulating complex ideas,
• responding to unexpected questions, and
• handling critique.

Whether in academic conferences, teaching scenarios, or even non-academic jobs, the ability to present and defend your ideas clearly and professionally sets you apart.

In the grand scheme, your thesis defense is more than just a formality. It’s a crucible that transforms years of research into a defended, deliberate statement of your academic capability.

It’s not just about answering questions; it’s about proving that your research stands up to scrutiny and contributes to your field.

What Happens In A Thesis Defense?

Thesis defense is a very long process. You start with months, sometimes years, of preparation, writing and completing your thesis.

You will defend your work before a committee usually made up of faculty members from your department, and possibly an external examiner. These are the experts in your field who will rigorously evaluate your research.

The defense itself is a formal yet dynamic process. It begins with you presenting your thesis, often through a detailed PowerPoint presentation. This presentation highlights:

• the main points of your research,
• your methodology, and
• your findings.

Think of it as a summary of your long journey—a chance to argue the significance and validity of your work.

After your presentation, the committee will ask questions. These aren’t just any questions; they are often complex, open-ended queries designed to test how well you understand your research and your ability to think critically under pressure.

You need to demonstrate not just knowledge, but a deep grasp of your topic and related theories.

An interesting twist is that you may be asked to leave the room after your presentation. During this time, the committee deliberates on your performance. They discuss whether you’ve met the high standards required for a PhD and whether your thesis contributes significantly to the field.

This can be a nail-biting time for many students, as the discussion behind closed doors determines the outcome of years of hard work.

If all goes well, they will call you in, and inform you that you have passed your thesis defense. At this point, you may hear yourself being addressed as a ‘Doctor’ for the first time. 

If theres hiccups, you pay still pass, but with corrections. This means you need to perform additional work on your thesis for it to be accepted. In worse cases, you thesis may require major corrections. Some examination panels may also require you to redo your thesis defense.

This is fortunately, not very common. This is because your supervisor would have ensured your work is up to par before submitting your application for thesis defense.

How To Prepare For A Thesis Defense?

Preparing for your thesis defense can be daunting. You’re about to present years of work to a committee that will scrutinize your research and knowledge. Here are ten tips to help you prepare for your thesis defense.

1. Understand the Format: Every university has its own rules for thesis defenses. Check with your advisor or the graduate office to understand exactly what’s expected of you. Whether it involves a public lecture or a closed session with your committee, knowing the format helps you prepare effectively.

2. Focus on the Core Ideas : Resist the temptation to include everything from your dissertation in your presentation. Highlight the most significant findings and methodologies. This approach helps you stay within time limits and keeps your audience engaged.

3. Anticipate Questions : Think about potential gaps in your research that faculty members might target. Prepare slides or notes that can help you answer these tough questions. This foresight can turn a difficult question into a demonstration of your thorough preparation.

4. Rehearse Extensively : Practicing your presentation multiple times is crucial. Try to simulate the defense environment as closely as possible, ideally in the actual room where you’ll present. This rehearsal will make you more comfortable and fluent during the actual defense.

5. Prepare Visually Clear Slides : Your slides should aid your presentation, not confuse the audience. Ensure they are clear, visually appealing, and free of clutter. Use diagrams, charts, and bullet points to effectively convey complex information.

6. Dress Professionally : First impressions matter. Dressing professionally respects the formality of the occasion and can also boost your confidence. A business suit is often the go to for most candidates, although some universities may be more relaxed on the dress code.

7. Create Backup Slides : Have additional slides prepared for deeper dives into specific topics. These are particularly useful if a committee member asks a detailed question about a particular point or method.

8. Know Your Committee : Research the interests and work of your committee members. This knowledge can help you anticipate the kinds of questions they might ask and prepare more targeted responses.

9. Stay Calm and Collected : Remember that defense is not just an examination but also an opportunity to showcase your work. If you don’t know an answer, it’s okay to admit this and suggest how you might find it out. This shows honesty and a willingness to learn.

10. View It as a Professional Dialogue : Approach your defense as a professional discussion rather than an interrogation. This mindset can change how you perceive the event, reducing stress and helping you engage more openly with your committee.

These strategies are about more than just surviving your defense; they’re about making the most of an opportunity to excel and impress

Prepare For Your Thesis Defense

Your thesis defense is not just a formality; it’s a bridge to your future career and a chance to shine. Prepare diligently, understanding that this is as much about demonstrating your grasp of the field as it is about honouring your own hard work.

With the right preparation, you’ll be able to defend your thesis with confidence and leave a lasting impression on your committee.

Preparing for your dissertation defense, published by steve tippins on april 4, 2019 april 4, 2019.

Last Updated on: 30th August 2022, 04:43 am

Preparing for your dissertation defense is one of the most important things you’ll do as a doctoral candidate. Now that you’ve completed your dissertation, it’s up to you to present the results to your committee.

However, the results aren’t just about your study. Your committee wants to see what you learned through the process and whether you are ready to take on the responsibility of being a scholar.

What is a Dissertation Defense?

When you finish your dissertation and your committee has said you are ready to move forward, there is a formal meeting–your dissertation defense–where you have the opportunity to explain what you did and what you found.

Your committee then has the opportunity to ask questions related to your work, the implications of what you found, and your future. It is a chance for you to stand before your peers and be welcomed into the academy. Defending your dissertation is one of the great rites of passage into the world of academia.

How to Prepare for Your Dissertation Defense

Rather than write a quick list of dissertation defense tips, I thought I’d create a comprehensive guide to defending your dissertation. After chairing and sitting on countless dissertation committees, these are the steps I recommend you take.

Cultivate The Right Attitude

Perhaps the most important thing to have as you prepare to defend your dissertation is a revised view of your academic self. You’ve spent years gaining knowledge on your chosen subject, and now is your time to shine. While it’s natural to be nervous — after all, you’re jumping the highest hurdle in academia — keep in mind that this is your moment to shine and that you are now an expert on the topic.

One way to look at the dissertation defense is as a rite of passage. You are being tested, and just as with any rite of passage, the more rigorous the test, the prouder you will be of making it through.

During the process of your defense, keep this in mind: your committee tests you not only to ensure your worthiness but also to enable you to see just how much you know; to step into your new role as “expert.”

Prepare For Your Committee’s Questions

With this attitude in mind, you will want to prepare to demonstrate your expertise. That means anticipating questions the committee may have about your research.

If your dissertation asserts the likelihood of a recession in the presence of particular economic indicators, your committee will want to know what socio-political conditions are linked to these indicators. If you found that high achieving students are more likely to have had parents who volunteered in their schools, your committee members will likely ask you to speculate about how to increase parent involvement in schools.

In other words, you’ll need to be able to participate in discourse beyond your results — questions that speak to the relevance and implications of your research.

This kind of preparation goes beyond creating a PowerPoint of your findings (though that is necessary too); it’s part of your stepping into your expert role.

One thing I always tell my students is “Be able to explain your topic to your grandparents,” because to elucidate someone who knows nothing about the topic (no offense to the grandparents!) you must know it inside and out.

Of course, you’ll also want to know your topic well enough to discuss the topic with the top researchers in the field, but at this stage, you’ll have read enough of their work that you’ll feel you know them personally. It’s usually more difficult for academics to simplify than to complicate.

To ready yourself for potential questions, give your abstract to a few friends outside your academic program and have them ask you questions about your study. The advantage is their “outsider” perspective; you’ll have fun answering their questions and will likely have to make a few new neuronal connections to do so. Practicing like this will also help you relax during the actual defense.

Here are some questions you may be asked during your dissertation defense :

• “What are the strengths and weaknesses of your study?”
• “What was the most surprising thing you found?”
• “What will you do next with your results?”
• “If you could do this over, what would you do differently?”

Organize Your Presentation

Keep in mind that your presentation to your committee can double as your presentation to the faculty at any university to which you apply; your preparation will serve a dual purpose. You’ll need, therefore:

• a concise overview of the literature in which your study is grounded,
• a clear description of your study’s purpose, methodology, and findings,
• and a discussion of the implications of these findings.

Naturally, you will need to consult your department’s and college’s specific requirements, but every dissertation committee (and faculty search committee) will want to fully understand these basic elements of your work.

I have provided a list of questions to help prepare your dissertation defense. If you have time restrictions I would put more emphasis upon your results and the implications of your work. Think of organizing your slides according to these questions:

1. Why did I choose to study this? Don’t be afraid to reveal something personal about your motivation, as long as you can do so with poise and dignity. Your committee members will appreciate this humanizing element but keep it brief!

2. What have other people interested in this topic found? If your study is the next clue in the hunt for answers about this topic, what were the clues that led you here? What paths have past researchers gone down — both fruitful and not? What solid theoretical foundation stands under your study?

This portion of your presentation is the easiest to overdo. You will likely need to edit it again and again to ensure it is both concise and comprehensive. Stick to the major themes in your presentation but be prepared to answer questions about less dominant streams of research.

3. How did my research question evolve? Answering this question links your research to what has already been established, placing your study in the stream of knowledge. Keep it brief but don’t skip this step, as it is key to showing you as an academic, rather than a student.

4. How did I organize my study? This is a description of the basics of your study and the “whys” of these choices. You can expand a bit here, as the decisions you made at this stage demonstrate your ability to think critically about approaching a research question. Why did you choose your particular methodology? What was the benefit of this design over another option you might have chosen?

5. What did I find? You can begin this section with what you expected to find and why, then explain what you actually found. Keep this section simple and factual.

6. What do the findings mean in relation to the question? Whether or not your findings matched your expectations, they tell you and your colleagues something important about the topic. What is it? Can we speculate that this is a promising area of research, or is this a path we might think of as a dead end? What, exactly, does this study tell us?

7. What’s next for me and for the research? You’ll want to give your committee (and any faculty search committee) a preview of your prospective academic career. What new questions has your study sparked for you? What would you hope other researchers would look at next? How do you intend to fit into the academic conversation on this topic?

Depending on your committee and requirements, you may want to include potential grants you will consider applying for to fund your next study. (This inclusion becomes more important when applying for academic positions.)

Prepare Yourself Mentally

Going back to attitude, remind yourself that a dissertation defense is your opportunity to step into your new role. This is your domain now. Breathe deeply and feel the pride that comes with a job well done. Know that you belong in this realm and the dissertation defense is your chance to prove it. Be humble, too; after all, you stand on the shoulders of giants.

Getting enough rest the night before, drinking water and bringing some with you to drink when your mouth gets dry, and being wise about what you consume prior to the defense (maybe go easy on the carbs and caffeine) are all obvious but frequently overlooked pointers. Your committee members want to know you can handle the pressure and take care of yourself under duress .

You might want to give yourself a few minutes of silence and rest before heading in to defend. Take those moments to recognize whatever you’re feeling, then humbly begin your academic career by presenting your most important work to date.

5 Ways to Combat PhD Stress

• By Nicholas R.
• January 8, 2024

When you’re starting your research career as an academic researcher, there will be many things that overwhelm you when you start out. As someone who has been through this myself, I have put together 5 ways of dealing with overwhelming feelings during your PhD journey.

These strategies may not work every time, but they’ve helped me get through my own struggles so far and hopefully can help you too!

1. Know What’s Going On

Before you dive into trying to solve any problem or figure anything out, take care of yourself mentally by knowing what exactly overwhelms you at the moment. One way to do this is to journal about what stresses you right now. When you feel more able to cope, try exploring solutions for those issues.

For example, if you find yourself struggling with managing workload, then it might be helpful to know that this type of stress often occurs at the very beginning and very end of a PhD, at least for myself and others I’ve spoken to.

Knowing the sources of your stress is the first step to addressing it.

2. Take Care of Yourself

Once you understand why you’re feeling overwhelmed, the next thing to consider is taking care of yourself physically. Stress from work, school, relationships etc., all contribute to poor health decisions such as skipping meals, engaging in unhealthy eating habits, drinking or smoking excessively, reducing sleep and exercise etc. All of which impact negatively on our physical and mental well-being.

In addition, one study showed that people under extreme levels of pressure (such as doctoral candidates) were more prone to developing heart problems compared to other groups. So while taking care of yourself should always be a priority, it’s especially important to prioritise it even further when we’re stressed.

It can seem difficult to balance personal needs and researcher responsibilities, but doing so requires prioritising self-care over everything else. In order to achieve this, set aside dedicated blocks of time each day where you avoid distractions, focus solely on activities related to your wellbeing, and allow yourself to fully engage in whatever activity brings peace to your mind and body.

3. Talk About It With Friends and Family

One thing that you learn early in a PhD is that there’s no such thing as a free lunch. While the rewards of doing your PhD are many, there is a significant cost, and it comes in the form of stress.

You’ve probably heard the expression “ PhD students are walking time bombs ” – which is basically just a polite way of saying that PhD students are walking around with a serious short-fuse, and it’s only a matter of time before that fuse goes off.

Seek support from others before that happens…

Talking to close friends and family members helps us to process emotions better. Research shows that talking to others provides relief by releasing negative thoughts and worries, so we don’t need to carry them around inside ourselves throughout the rest of the day. Having supportive individuals in our lives makes it easier to handle both small tasks and large ones.

If you live alone, however, having someone available to discuss your concerns with can provide valuable insight into whether or not you’re handling stressful events properly. A friend or family member can offer perspective and guidance without judging you for your current situation.

4. Make Time For Fun Activities

We’ve all heard that it takes 10 years to make a really brilliant scientist. You might have trouble proving this, but it is a very long time, and many people struggle with sticking to a research plan that is longer than 3 months.

We also know that there are many distractions available in the ‘real world’, that are not available to researchers. A few months ago, for example, I went to a pub quiz night. While this may sound like a total waste of time, in fact it has become a huge amount of fun for me, and has helped me to get my research into the right place.

I also find that regular, non-research-related social events help keep things fresh and remind me that there are more important things than my research at the moment.

5. Accept That This Is Just Part Of The Process

The hardest part about completing a PhD program is simply surviving it. Many of the lessons learned along the way will come from overcoming obstacles and failures. Learning from setbacks and mistakes prepares us for future success. But sometimes, no matter how hard we try, we just won’t be successful at accomplishing certain milestones or reaching our desired outcome.

That doesn’t mean giving up though. Instead, accept that failure can happen and move onto bigger opportunities. Sometimes we learn more from our successes and achievements rather than focusing on our failures and shortcomings. Also, remember that setbacks aren’t permanent. Often, after a short period of mourning, we bounce back stronger than ever.

We shouldn’t beat ourselves up over failing. Rather, let it inspire us to become wiser and smarter for next time. After all, it takes countless attempts to master the skills required to succeed.

Regardless of how you’re feeling, remember that you are not alone. You are not alone on your PhD journey. You are not alone in your feelings. And you are not alone in your desire to succeed.

A concept paper is a short document written by a researcher before starting their research project, explaining what the study is about, why it is needed and the methods that will be used.

Preparing for your thesis defence

As you start thinking about the end stages of your PhD, it’s important to understand the processes and timelines related to the thesis defence.

Even if your defence feels far away, there are steps you can take early on in order to ensure that the end of your PhD and defence process runs smoothly.

Jump to: What is a PhD defence? | Who's at the defence? | What happens at the defence? | What are the possible outcomes of the defence?  

What is a PhD defence?

The thesis defence is a unique opportunity to share with other experts what you did as part of your PhD research, what you found or discovered, and why it’s important. Although there are a lot of regulations guiding the defence process, remember that this process is really about you and your work.  

Goals of the PhD defence:

• Allow you to show your mastery of the subject matter
• Prove you are the author of the world
• Demonstrate your ability to engage in scholarly discourse in your research area

Who's at the PhD defence?

The primary attendees of your PhD defence are the Chair of the defense and your examining committee. The Chair is an impartial faculty member from outside your department who is well-versed in the rules and proceedings of thesis examinations. The Chair does not question you and does not assess your work.

Examining committee:

• Supervisor(s) - Your thesis supervisor(s) that have supervised your research.
• Internal member - A member of your department; typically part of your advisory committee.
• Internal/external member - An "internal" member of the university, but "external" to your home department. This person has suitable knowledge of the subject matter, even though they are from another discipline.
• Additional member - Typically a member from your advisory committee.
• External examiner - A person with a doctoral degree and expertise in the subject matter who evaluates the thesis from a fair an impartial perspective.

At University of Waterloo, it is also standard to have defences open to the public, so you can invite your friends, family and colleagues to be there! Check with your department to figure out what options are available to you.  

In some cases, such as when there are intellectual property concerns, a closed thesis examination can be requested. This means that all those in attendance at the thesis examination, including the examining committee members, must sign a non-disclosure agreement.  Closed examinations must be requested as early as possible.

What happens at the defence?

The first component of the defence is the welcome. The Chair will open up the defence, go over the order of proceedings, introduce the examining committee, and welcome the attendees.

After the welcome, the examination will formally begin with your oral presentation. The presentation is no more than 30 minutes, but the exact length and format can vary by department or discipline. It's best to check with your supervisor to confirm departmental expectations, but overall, the presentation should focus on your main contributions and conclusions. 

The final component of the defence is the questioning period. This is not meant to be an interrogation, rather, a discussion amongst colleagues about the subject of your thesis.

• The examination Chair monitors the question period, which goes in "rounds".
• During the first round of questioning, each committee member will have 15 minutes to ask their questions, provide their comments, and discuss these with you.
• After each committee member has had their turn to ask questions, there may be additional rounds for more questions. The Chair and committee decide when the questions will end.
• Typically, the Chair will reserve some time at the end to accept questions from non-committee members.

While there is no set time for defences at the University of Waterloo, they typically range from 2-3 hours. 

What are the possible outcomes?

Once your formal defence has concluded, the examination Chair will arrange for a private deliberation between the committee members. The examination committee's decision is ultimately based on your written thesis, as well as your ability to defend it, as the decision is determined by a majority vote.

In the event of a tie decision, or if the external examiner's vote is not in the majority, the decision will be deferred to the Associate Vice President (AVP), Graduate Studies and Postdoctoral Affairs. The AVP will consult the Faculty Associate Deans and come to a final decision. 

Once the deliberation has concluded, the Chair will inform you of your examining committee's decision.

There are three possible outcomes to a PhD defence:

• Accepted: The thesis is completed to the satisfaction of the examining committee. There may still revisions required, but they are likely minor and typographical or editorial in nature. In this case, you would have one month to complete all revisions and submit your approve thesis to UWspace.
• Accepted conditionally: The oral defence and the thesis are acceptable, but content changes are required that are time intensive. In this case, you would have four months to complete revisions to the approval of your committee and submit the final version to UWspace. A re-examination is not required. 
• Re-examination: The oral defence is not to the satisfaction of the committee and/or substantial changes to the thesis are required. In this case, the candidate must be re-examined within 1 year. 

Re-examination is very rare, and the vast majority of candidates have their thesis accepted at their first examination.

Thesis defense: tips and know-how

If you are preparing to defend your thesis, you’ve come to the right place! This guide explains some pointers to consider when preparing for your thesis defense, both prior and during the thesis presentation. Before we can begin discussing some tips and best practices for preparing a thesis defense, we first need to define and differentiate between the different types of defenses that exist. Doctoral defenses (PhD defenses) follow a different format than bachelor or master thesis defenses. The format tends to vary greatly, depending on the country, so there are is no one size fit all policy with regards to the structure. There are however some general guideliens that are important to consider, regardless of the format.

What is a thesis defense?

The thesis defense, also known as thesis presentation or disputation in certain countries, signifies what is often the last and final part of your thesis journey. This is your moment to shine, where you are the center of the stage, to promote your thesis and discuss your results and your research. To some, this event is stressfull, particularly those who prefer not to speak in front of others (see our guide on public speaking) and for others, it’s an opportunity to finally be able to let the world know what you have been up to for the last few months (for master/bachelor theses) or for the last few years for PhD/doctoral theses work.

So how do we learn how to deliver a good thesis defense?

Learn from the mistakes of others…

Many years ago, when I was still in the early phases of my PhD, one of my academic supervisors, a late Professor of Civil Engineering, suggested that I enroll in a dissertation analysis course. The “course” was comprised of me sitting through several thesis / dissertation defenses and jotting down anything that I could learn from them. This included, how well the PhD candidate defended their thesis, what kind of criticism or points were reoccurring, and any other observations that I had regarding the thesis defense. This proved to be a very valuable exercise. This is an exercise that you can (and perhaps should) undertake yourself, not in a formal “course” setting, but rather by listening in and taking part in other peoples’ public thesis defenses. Although not all thesis defenses are public, most tend to be, and there is a lot that you can learn by observing the defense from the point of view of the audience.

So how do you find a thesis defense to listen in on?

The best case scenario would be to listen to theses defenses delivered by students in the same research area and university, if that’s not possible, a different thesis topic but still fairly tangential to your research area would also be useful. These days (I am writing this guide during the covid pandemic of 2020/2021), it is extremely easy to take part in thesis defenses online via Zoom as they are often publicized in advance and can be found by browsing your universities’ online events calendar.

So what did I learn through the numerous theses that I listened to?

The first thing I noticed that was a recurring theme, a question that seemed to appear in all the theses defenses that I attended, had to do with how the student’s work contributed to their research field. What is special with your research? What new findings have you been able to lay forth; or which previously known findings have you been able to amend? This is the the central point that all of your research enquires revolve around, the raison d’être of your research, what are the contributions that you are bringing, and why should we care?

Of course, the bar is much set much higher for doctoral theses work compared to bachelor and master thesis, but the point still stands. This does not mean that each and every thesis that is published needs to be groundbreaking and ignite a paradigm shift. In fact, most thesis work do not lead to any revolutionary contributions. This point is perhaps best illustrated by satirical web sites such as lolmythesis where students submit their real thesis titles alongside a more comical title in plain English. This gives rise to titles such as this one from Yale University with the plain title “UAV deployment for fine-scale CO2 estimation in a mid-size city” which the author claims could also be titled as “I collected all my data then realized I didn’t record the variables needed for the one thing I promised to do in the title of my thesis”.

Do not stress over the significance of your research contributions, but do be prepared to defend them publicly.

What concrete contributions can you claim came about as a result of you having done this study of yours? If you can not answer that question (or at least explain why why your results were or were not remarkable), then you are out on dangerous water. There is an expectation that these contributions that we bring should actually have some form of substance, which they unfortunately do not always have. The site lolmythesis is a testimony to that, it perfectly encapsulates what it means to publish theses. Here are some more examples to put your mind at ease:

Keeping a strong mind set

The table above reminds us not to take things too seriously. If you feel that your results are underwhelming, you may consider yourself a member of the academic club, everyone tends to produce results at one point in their research career that they themselves consider underwhelming. For the defense however, the key here is not to focus on the results themselves, but rather on the overall arguments and the overarching discussion that surrounds your results and provides a context to your key points. Be ready to defend and explain anomalies in data, or the specific choices that you made with respect to why you chose a specific research method instead of another. The thesis defense should be viewed as an exercise for you to be able to explain your overall argument and show why it is consistent. Remember that the thesis defense does not exist for you to be criticized with regards to other peoples data or research. As long as you have a strong grasp of your own research topic, you should be able to breeze through the defense. You can feel assured that (for most cases) no external expert or review committee will know more about your specific thesis than you do. As long as this disparity in knowledge holds true, it doesn’t matter how much more they know about the overall research field, if you are more knowledgeable of your specific research inquiries and their underlying assumptions.

The second point that I want to highlight is that all of your conclusions should follow from the results that has been presented (which in turn come from the data that you collected, depending on research area). With other words, all of the conclusions that are mentioned should follow logically from the underlying premises. I remember once attending a thesis defense where it was clear that the doctoral student highlighted certain conclusions that had no basis in the person’s data, and that sort of things tends to get highlighted real fast. So you need to be careful about that.

The third point concerns quality. The work must of course be of high quality, this is understood by all, but it also means that the data was gathered properly and that the sources that you cite are relevant and authoritative. Make sure that the image/story that you are presenting during your defense is internally consistent. Thus, even if an opponent has issues with a specific method that you chose, they cannot claim that your research contradicts itself. Apparent contradictions can be very problematic, and if you suspect that there might be a contradiction somewhere in your thesis, you need to be ready to explain that paragraph if asked to.

The last thing I want to mention has to do with the mental state of the one who is presenting. There is no doubt that public speaking is stressfull for a lot of people, and it is therefore extra important to remember to not place to much weight on the matter. It is after all only a speech. You know the topic, why worry, you literally wrote a book on it! As one says in swahili, hakuna matata is an appropriate attitude to have towards the thesis defense. It is important to remember that studies, specifically doctoral studies, are more than just a written dissertation. Instead, it encapsulates the whole process where you gradually learn more about your specific research work. Regardless of whether you achieve a undergraduate, postgraduate or doctoral degree at the end of your research, that degree only symbolizes the start of a learning journey, and not the end. Unlike the common conception, PhD studies shouldn’t be viewed as a dreadful and draining undertaking that finally culminates in this large-scale orgasmic metamorphosis where you are transformed from this lowly caterpillar to become a fully-feathered and competent butterfly.

The list below contains a few links to real examples of theses defenses. Do check out the presentation by Dr. Ben Conrad which is really good example of a thesis defense done right, it manages to be informative, to the point as well as engaging the audience and the material.
