Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

If you want to learn more about dissertations in your own discipline, don’t hesitate to reach out to graduates from your program and ask them about their experiences.

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.

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

• I. Daniel Posen Defense Slides with Notes

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator. 

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

• What is your study about and why did you choose to research this in particular?
• How did your research questions evolve during the research process?
• How did you decide on which sources to include in your literature review?
• How did you design your study and why did you take this approach?
• How generalisable and valid are the findings?
• What were the main shortcomings and limitations created by your research design?
• How did your findings relate to the existing literature?
• What were your key findings in relation to the research questions?
• Were there any findings that surprised you?
• What biases may exist in your research?
• How can your findings be put into practice?
• How has your research contributed to current thinking in the field?
• If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

• What exactly were you asking in those questions, and what did your research uncover concerning them?
• Which questions were well answered by your study and which ones were lacking?
• Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future . This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

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.

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.

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

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.

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.

Once you have submitted your dissertation, you may be asked to do a defence of your dissertation. This could be in the form of an oral presentation, a poster presentation of your findings, or you could be invited to a viva voce. Vivas, as they are usually known, are particularly common for research degrees such as MPhils or PhDs and are essentially a verbal defence of your thesis that is conducted in an interview style format. At a minimum, the viva is a way of checking you authored the thesis yourself and understand the detail, but it is also an opportunity to discuss your research findings and interpretations in depth with experts. Preparation is key for defending your thesis in a viva or a presentation format. With a bit of groundwork, you could even enjoy the discussion, after all the thesis is the culmination of all your hard work, and no one knows it better than you.

Trapped in dissertation revisions?

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. And then get ready to roll up your sleeves for the next one. Congratulations, Doctor!

What’s the best way to prepare for your PhD thesis defence? The tips below will help you in the final few weeks before the exam, but the real preparation begins as soon as you start your PhD . Talking to people and discussing your work regularly over a long period of time is the best preparation, so don’t let your thesis defence be the first time you get feedback on your work!

Know the format of your PhD thesis defence

The format of a PhD thesis defence varies from country to country. Having studied in the UK, my viva-voce defence was essentially an interview with one internal and one external examiner. In other countries, it’s common to have public examinations with a whole panel of examiners and an audience of colleagues, family and friends. The first and most obvious tip, then, is to make sure you know what the format of your exam will be; whether you will have to prepare a presentation and so on.

Prepare and practice your presentation

If you have to give a presentation, check any time restrictions so you can prepare accordingly. You don’t want to show up with 100 slides for a 15-minute presentation, nor do you want to show up with 3 slides for a 1-hour presentation.

The most important thing to do for any presentation is to practice so that;

• You know the material inside out
• You know how long it takes
• You can refine the presentation

You can practice on your own or with an audience, and you should do both if possible. Practicing on your own and speaking out loud to an empty room may feel silly, but overcoming that discomfort is good preparation for the discomfort of facing an actual audience. Practicing with an audience of peers is then a good way of getting feedback and finding out what questions people ask.

The dreaded “awkward question”

A common fear is being asked a question you can’t answer. It’s tempting to try to read a ton of literature to prepare for this, but since it’s very difficult to predict what the examiners will ask and it’s impossible to read everything, this approach isn’t always effective or reassuring (it might just make you realise how much you don’t know).

You aren’t expected to know everything. Sometimes, an examiner will ask a question they don’t know the answer to, either out of interest (since you are the expert in your research) or because they want to see how you think. While it is OK, sometimes, to just say “I don’t know”, you could also say something like,

‍ “I don’t know, but I would think that […] 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.

Core content

Of course, there is some core content which you will be expected to know well, but this is set by you, not the examiner. To a large extent, the content of the examination is determined by the content in your thesis.

When you choose what to cover in your thesis you are choosing your battleground for the thesis defence. The best strategy, then, is to stick to the material you know best in your writing!

Dealing with nerves in your thesis defence

You will be nervous before your examination. You will almost certainly get an adrenaline rush, which can set your heart racing, give you sweaty palms, make your stomach churn and make you want to go to the toilet 10 times in 20 minutes. This is normal!

The worst part is waiting to start because there isn’t much you can do to use up your nervous energy. But once the defence starts, you can do some things to keep it under control.

One symptom of nerves is to talk really fast and to try to show how much you know and speak in this kind of long stream of consciousness that diverges away from the question until you forget what the actual question was but then you don’t know how to get back to the point and so you just keep talking and that makes you more nervous and how are you going to get off this train of thought…

Try to slow down and give yourself time to breathe. Try to remember the question* and come back to the point. Once you have answered, stop talking!

*If you forget the question, it’s OK to say, “sorry, I got lost in my train of though there, what was the question, again?”

The examiners expect you to be nervous

Remember that the examiners expect you to be nervous, and they will help you through if necessary. It’s OK to ask them to repeat or clarify a question, to pause to think, or to take a sip of water if you need to!

Ultimately…

Success or failure is determined mainly by the content of your thesis. If your research is good, and you actually did the work, it’s unlikely that a nervous performance in your defence will lead to failure. Generally speaking, once your thesis is submitted, there isn’t much you can do to affect the outcome (positively or negatively). Read through your thesis, read up on one or two key points if necessary, practice your presentation, and trust that whatever happens you will be OK.

Defense and Dissertation Overview

Once a student’s box is checked, the BPH student should set up a one-on-one “Defense Packet Meeting” with the BPH Associate Director to review the Defense and Dissertation Process, which includes reviewing all required materials, logistics, timing, FAS/Harvard Griffin GSAS Form of the Dissertation, sample forms, and to answer student questions related to these processes.

• Defense Committee Chair: One member of the student’s DAC, often the DAC chair, is required to chair the oral defense. This required holdover from the DAC serves the purpose of providing insight to the examiners regarding the path the student has taken in completing the dissertation research. Their primary role is to assess committee satisfaction with the written dissertation, administer the exam, arbitrate any problems that may arise, and make final recommendations for completion of necessary corrections and additions to the dissertation. No other DAC members can serve on the defense committee .
• At least one member must be a BPH faculty member, often from the same academic department.
• One member of the examination committee must be from outside of Harvard University.
• The fourth member may be from either BPH or another Harvard-affiliated program.
• Co-authors and collaborators cannot be members of the Defense committee

DEFENSE TIMING AND FORMAT

• Students should notify the BPH Program as far in advance as possible with the details of the exam. 
• The student is required to notify the BPH office no later than 3 weeks in advance of the defense with the final dissertation title.
• At least two weeks before the date of exam, defense members should be sent copies of the dissertation for review. A copy of the dissertation should also be sent to the BPH program.
• If any defense committee member foresees problems with the exam, they should contact the chair of the defense committee in advance of the meeting. If major problems are found with the written document, the Committee can decide to postpone the oral defense until satisfactory changes are made. While rare in our program, these occasions can involve the insufficient or improper use of statistical methods, grossly overstated conclusions, insufficient background or discussion, or evidence of plagiarism.
• More details about the timing and format are provided in the “Defense Packet Meeting” held with each student.

STIPEND GUIDELINES

If a student successfully defends the dissertation before the 15th of the month, the stipend will be terminated at the end of that month. If the student successfully defends on or after the 15th, the next month’s stipend will be the final month the student is paid, at the discretion of their advisor.

Students are encouraged to speak to their advisors directly about how they should be paid as they complete their graduate work. If an advisor wishes to pay the student for one additional month, beyond what has been explained above, the advisor must notify the department’s financial administrator. For administrative reasons, a stipend cannot be issued to a student after their graduation/degree conferral date.

ORAL DEFENSE PROCEDURES

Part 1: Public Seminar As part of the exam, the PhD candidate will present a public seminar followed by a private oral examination.  The public presentation lasts no longer than 1 hour, which includes time for the advisor’s introduction, the student’s oral presentation and acknowledgements, and time for audience questions and answers.  The Defense Committee is required to attend the public seminar; however, it is customary for members of the defense committee to hold their questions until the private oral exam.

Part 2: Private Oral Examination A private oral examination follows the public seminar.  Initially, the student will be asked to leave the room for several minutes, along with the dissertation advisor if the dissertation advisor has decided to remain for the private exam.  During this time, the committee will discuss the merits of the dissertation, any issues with the dissertation, and areas they may want to focus on during the oral exam.  The student (and advisor if present) is then asked back into the room for the exam.

Each member of the defense committee will direct questions to the candidate based on their review of the dissertation and presentation of the seminar. The Defense Chair will moderate the discussion between the panel and the student.  The closed defense takes up to two hours and involves detailed technical questions as well as broader questions on the conclusions, impact, and limitations of the research.  Dissertation advisors may be present, but they must not participate in the exam (e.g., answer questions posed by the committee).

At the end of the examination, the student (and advisor if present) is once again asked to step out of the room for several minutes.  The Committee will discuss any revisions needed for the thesis and whether these revisions need to be reviewed and by whom.  Once the committee determines the outcomes, the student will be asked back into the room and the Committee provides the student with any [minor] changes needed to the dissertation. While it is extremely rare for the student to fail at this stage, the committee will provide recommendations to the student on their research, communication skills, and development as a scientist, as well as delineating the required changes to the dissertation.

PREPARING FOR THE DEFENSE/WRITING THE DISSERTATION

Students preparing to write and defend their dissertation must review University requirements as outlined in “ Dissertations ” with guidelines published at the Graduate School of Arts and Sciences.

Students are also welcome to visit the BPH Student Lounge (Building 2, Room 113) to look at copies of previous BPH bound dissertations.

Writing the Dissertation Each student must write a comprehensive PhD dissertation on their research topic and the original results of their research. There are a variety of ways a dissertation can be composed, but the core elements described below must be included. The dissertation must show original treatment of the subject, contain a scholarly review of the pertinent literature, provide evidence of independent research of publishable quality, and be clearly, logically, and carefully written. In addition to a compendium of the student’s research, including detailed methods and results, the dissertation must contain a thoughtful discussion of the conclusions, impact, and limitations of the research. The completed work should be critically reviewed by the dissertation advisor before being submitted to the Dissertation Defense Committee.

In some cases, the student has done all of the work in the dissertation; more often portions of the dissertation result from collaborative research. In all dissertations containing collaborative results, the dissertation should indicate concisely who contributed to the work and how.  For example, a chapter containing multi-authored, published work must include a complete reference of the publication and a brief description of the candidate’s and the colleagues’ contributions. For work that is not published but which resulted from multiple researchers, the contributors must be named and respective attributions made clear. This policy allows stylistic flexibility; depending on the amount of collaborative work in the dissertation and the status of publication(s), the attributions can be, preferably, on or accompanying the cover page for each chapter or within an extended acknowledgements section at the end of each chapter. It is recommended that if figures or figure panels are included that are the work of others that the figure panels be clearly identified and the work properly attributed. It is permissible for more than one student to include work from the same collaboration or publication as long as the required attributions are clear, justified, and complete.

Individual chapters can be that of published articles as long as there are also comprehensive Introduction and Conclusion chapters written by the student. While the text can be the same, use of journal reprints as a chapter is not permissible. A word document of the published article must be used, and the pages in the dissertation must be consecutively numbered. Furthermore, the figures and accompanying figure legends must be integrated into the main body of each chapter, preferably following the first mention of the given figure, not clustered at the end of the chapter. Any dissertation that varies significantly from the Graduate School or FAS guidelines, or is not neat and readable, is subject to required stylistic revision before acceptance by the University. (For further information, please visit https://gsas.harvard.edu/academics/dissertations ).

DEFENSE FORMS AND PAPERWORK

Dissertation Acceptance Certificate Before the examination, the BPH Program Office will provide the Defense Committee Chair with a copy of the official Dissertation Acceptance Certificate. This certificate must be signed by all readers of the dissertation at the end of the examination and returned to the BPH Program Office. This certificate will be scanned and sent to the student so it can be inserted as page one of the dissertation prior to the online submission. The student must submit the one original, official copy to the Registrar’s in Cambridge by the appropriate deadline.

If extensive corrections are to be made, the BPH Program Office will hold the certificate until the Defense Committee Chair, and/or assigned reviewer(s) provide a written notification to the BPH Program to confirm that the corrected work has been reviewed and approved.

Dissertation Defense Exam Report The Dissertation Defense Exam Report is completed by the members of the Dissertation Defense Committee to provide a record of any comments or recommendations they may have. The report must be signed by all members immediately after the private exam. The completed report must be submitted to the BPH Program Office at the same time as the Dissertation Acceptance Certificate.

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.

Dissertation Defense

The following steps are meant to help you begin thinking about your defense, dissertation, and eventually graduation. Please contact the Student Services Office if you have any questions about the process or requirements.

Planning Your Dissertation Defense

Steps for planning your defense.

Meet with your committee and determine a date and time. Some faculty travel extensively, so it is a good idea to start this process early.

Once you have a confirmed time, contact the Student Services Office. They will help in booking rooms for both the public and closed door sessions.

Tip : Some faculty travel extensively, so it's a good idea to start this process early. Room reservations can also be tricky depending on the time selected. The more notice you can provide, the more likely one of your top choices for rooms will be available.

Your chair must be someone outside of the department who is an Academic Council member. Your Oral Examination Committee must have a total 5 members including the University Chair. If you need help finding one, your advisor and other committee members should be able to help. University policy regarding chairs and your committee can be found in the  Stanford Bulletin .

Deliver a draft of your dissertation to each of your committee members 30 days prior to your defense. Some committee members may prefer just an emailed draft, however others may prefer a paper copy so be sure to check on preferences of each of your committee members!

Bring your University  Oral Examination Form  to the Student Services office (Gilbert 118 or via email) at least 2 weeks before your defense. The Student Services Office will bring this back to you or your advisor at your defense.

If you’d like the Student Services Office to create and post flyers for your defense, please send them a picture to use and your title 2 weeks before your defense.

Following your defense, please turn in the University Oral Examination Form to the Student Services Office as soon as possible.

Application deadlines vary by program, please review the application deadline chart for specific programs. Other important dates and deadlines can be found by using the One Stop calendars .

An applicant must meet  Graduate School requirements  plus these program requirements to be considered for admission to the program:

• Applicants holding a MS degree in computer science will generally be admitted without deficiencies. Applicants holding a BS degree in computer science may be admitted only if they are exceptionally strong, such as with a record including successful completion of courses normally taken at the graduate level in computer science.
• Applicants holding MS degrees from domains outside of computer science may be admitted with specific program-defined course deficiencies, provided that the deficiencies amount to no more than two courses. The student is expected to satisfy deficiency requirements within three enrolled semesters. The deficiencies are monitored by the Graduate School and the division of Computer Science. No course credits earned in making up deficiencies may be counted as program credits required for the degree. The mathematics preparation must generally include mathematics equivalent to MATH 231 . Otherwise, the made-up deficiencies must be sufficient to assure that the applicant is able to proceed with advanced work directed toward the doctoral degree.
• A minimum grade point average of 3.0 on the basis of 4.0, in the highest degree granted. An applicant with a master’s degree in engineering or computer science having a GPA of less than 3.0, but at least equal to 2.75, may be admitted if substantial evidence can be submitted demonstrating that the applicant has the capacity to perform satisfactory doctoral work.
• All applicants are required to submit a brief (1 or 2 page) statement describing their professional goals and at least two letters of reference.
• The Graduate Record Examination (GRE) is required for all international and domestic applicants.
• International students require proof of English language proficiency. Complete information is available at the  UWM Center for International Education .
• Applicants with a relevant master’s degree who intend to complete an additional master’s in Computer Science at UWM should announce their plans at the time of admission, and not later than the start of their second year into the PhD program.

Reapplication

A student who receives a master’s degree at UWM must formally apply for admission to the Graduate School as a doctoral student before continuing studies that will be credited toward the Doctor of Philosophy in Computer Science.

The minimum degree requirement is 66 graduate credits beyond the bachelor’s degree. The minimum credit  distribution of coursework to be undertaken must be as follows depending on the option selected.

The 6-credit requirement in mathematics and/or quantitative methods may be met by satisfactorily completing certain courses specified by the Department or by taking the minor in mathematics. When such courses also count for either the major or the minor area, the remaining credits may be taken as approved electives.

The student must achieve a 3.0 GPA separately in each of the following areas: the major area, the minor area, and the quantitative methods area.

The minor is normally in another area offered in the College or in the physical sciences or mathematics or in management sciences. Consideration of any other area as a minor requires the prior approval of the Department.

A minimum of 26 credits, excluding doctoral thesis, must be at the 700 level or higher.

Major Professor as Advisor

The Graduate School requires that the student must have a major professor to advise, supervise, and approve the program of study before registering for courses. The incoming student will be assigned to an initial Program Advisor at the time of admission. Prior to the completion of 12 credits (9 credits for part-time students), the student must select a major professor who will be the student’s thesis advisor. The student, in consultation with the major professor, develops a proposed program of studies which is submitted for approval. For subsequent changes, the student must file a revised program of study for approval.

Foreign Language

There is no foreign language requirement for the degree.

The program residence requirement is satisfied either by completing 8 or more graduate credits in two consecutive semesters, exclusive of summer sessions, or by completing 6 or more graduate credits in each of three consecutive semesters, exclusive of summer sessions.

Qualifying Examination

Each student in the program must take and pass a Qualifying Examination to demonstrate that the student is qualified for doctoral-level work. The Qualifying Examination is a written exam and is structured in two parts: Part 1 and Part 2. The examination is offered twice a year during the regular academic year. 

Students entering with only a bachelor’s degree or with a master’s degree in an area unrelated to their major may take the Qualifying Examination for the first time after earning 12 credits of graduate work at UWM and must successfully pass the exam before earning 30 credits of graduate work at UWM.

Students admitted after completing an appropriate master’s degree must take this examination no later than the semester immediately after 18 credits of graduate work have been earned at UWM.

A student may take the Qualifying Examination twice. On the first attempt, the student must attempt both Part 1 and Part 2 of the examination.

• If the student passes both parts, then the student has passed the entire examination and will be permitted to proceed toward the Doctor of Philosophy degree.
• If the student fails both parts, then the student must take the entire exam again at its next offering.
• If a student passes only one of the two parts, then the student must take the examination again at its next offering, but may choose to take only the part of the examination that was not passed on the first attempt.
• If a passing grade is not obtained on the second attempt of the Qualifying Examination, the student will not be permitted to proceed toward the Doctor of Philosophy degree.

A student who fails the qualifying exam twice is subject to dismissal from the PhD in Computer Science program. A student may appeal the failure and dismissal within 30 days of being notified of the failure. If the student does not appeal or the appeal is not granted, the College will recommend to the Graduate School that the student be dismissed. A student who is dismissed from the PhD in Computer Science program because of failing the qualifying exam may not be enrolled in the PhD in Computer Science program for a complete calendar year. This does not preclude the student from being enrolled in any other degree program offered by the University. A student who wishes to re-enroll in the program after a calendar year has passed must apply as any other student would, including payment of fees. A student readmitted after having failed the qualifying exam twice must take the qualifying exam in the first semester of matriculation and this will count as the student’s first attempt at the exam. The student may appeal this requirement prior to the first scheduled day of classes. If the student fails the qualifying exam on this first attempt, the student is permitted the customary second attempt as described above. All appeals must be in writing and directed to the CEAS Associate Dean for Academic Affairs.

Doctoral Program Committee

The Doctoral Program Committee is proposed by the major professor in consultation with the student and the department. The Committee must include at least five graduate faculty (three from major area, one from minor area, and one from any area, including the major and minor areas). The last member may be a person from outside the University (such as another university, a research laboratory, or a relevant industrial partner), provided that person meets Graduate School requirements. The Committee may have more than five members, provided that the majority of the Committee members are from the student’s major field.

Doctoral Preliminary Examination

A student is admitted to candidacy only after successful completion of the doctoral preliminary examination conducted by the Doctoral Program Committee. This examination, which normally is oral, must be taken before the completion of 48 credits of graduate work toward the Doctor of Philosophy degree in Computer Science and should be taken within the first seven years in the program. Prior to the examination, the student must present a proposal for a doctoral dissertation project. The examination may cover both graduate course material and items related to the proposed dissertation project.

Dissertation and Dissertator Status

The student must carry out a creative effort in the major area under the supervision of the major professor and report the results in an acceptable dissertation. The effort of the student and the major professor to produce the dissertation is reflected in the PhD in Computer Science program requirement that the student complete at least 18 credits of doctoral thesis. 

After the student has successfully completed all degree requirements except the dissertation, the student may enter Dissertator Status. Achieving Dissertator Status requires successful completion of the Doctoral Preliminary Examination and prior approval of the student’s advisor, the Doctoral Program Committee, and the Computer Science GPR of a dissertation proposal that outlines the scope of the project, the research method, and the goals to be achieved. Any proposal that may involve a financial commitment by the University also must be approved by the Office of the Dean. After having achieved Dissertator Status, the student must continue to register for 3 credits of doctoral thesis per semester during the academic year until the dissertation is completed.

Dissertation Defense

The final examination, which is oral, consists of a defense of the dissertation project. The doctoral defense examination may only be taken after all coursework and other requirements have been completed. The student must have Dissertator Status at the time of the defense.

All degree requirements must be completed within ten years from the date of initial enrollment in the doctoral program.

Alexander Shearer PhD Thesis Defense

Nucleation engineering of ald for microelectronic applications, event details:, this event is open to:.

Alexander Shearer PhD Candidate Chemical Engineering Academic advisor: Prof. Stacey F Bent

Abstract: Nucleation Engineering of ALD for Microelectronic Applications

In accordance with Moore’s law, semiconductor devices have been shrinking for over 60 years, driving exponential advances in computing. However, as we approach the atomic limit of scaling, new challenges are arising in both the materials we use in devices and the way we fabricate them.

One critical challenge in the miniaturization of semiconductor devices is the physical limitations of silicon. When scaled down, silicon devices experience short channel effects and mobility degradation. This has motivated the exploration of alternative semiconductor channel materials, such as 2D transition metal dichalcogenides (TMDs). TMDs are atomically thin materials with pristine surfaces and tunable bandgaps – making them excellent candidates for maintaining high electrical performance at the ultra-scaled limit. Despite their potential, integrating them into devices poses numerous challenges – one of which is the integration of a dielectric by atomic layer deposition (ALD). The inert surfaces of TMDs hinder nucleation of materials by ALD. As such, engineering of the ALD process is necessary to facilitate the deposition of a high-quality oxide on a TMD for nanoscale device applications.

Simultaneously, the top-down photolithography process used to pattern these ultra scaled devices is reaching its limits, with issues like misalignment of nanoscale features becoming a bottleneck for device performance and reliability. Area-selective atomic layer deposition (AS-ALD) offers a promising solution by enabling a bottom-up approach to nanopatterning. AS-ALD exploits differences in surface chemistry and the nucleation behavior of ALD to promote growth on specific surfaces and hinder it on others, creating self-aligned features. Despite its promise, more work is necessary to make AS-ALD feasible for industrial applications.

Both of these challenges – dielectric integration on 2D materials and nanopatterning for advanced device architectures – rely on the precise manipulation of ALD nucleation behavior. This defense presentation will explore strategies to control and optimize the nucleation behavior of ALD for two primary objectives: (1) enabling area-selective deposition for robust and scalable nanopatterning and (2) achieving high-quality dielectric integration on TMDs. By focusing on the underlying principles of nucleation control, this work aims to advance the application of ALD in overcoming key hurdles in next-generation semiconductor device fabrication.

In the first part of this defense presentation, a new inhibitor, benzenethiol (BT), is introduced for enabling AS-ALD of ZnO on SiO2 in the presence of Cu and CuOx. BT forms a monolayer on Cu and a thick, semicrystalline multilayer on CuOx composed of 1D Cu-thiolate coordination polymers. Both the monolayer and multilayer structure provide excellent selectivity – with the multilayer structure facilitating the creation of thick, self-aligned features on nanoscale patterned substrates.

The second part of the defense presentation expands upon the work with the BT inhibitor. BT is used to selectively deposit Al2O3 on SiO2 and not on Cu or CuOx using a series of Al precursors. It is found that the choice of precursor dramatically impacts the selectivity achieved, with one precursor facilitating near-perfect selectivity indefinitely, and the others failing to provide any selectivity at all. It is hypothesized that some precursors become miscible in the BT inhibitor layer and catalyze its degradation, leading to nucleation on top and throughout the inhibitor layer. The miscibility is found to be ligand-dependent, leading to a range of degradation and nucleation behaviors.

Finally, in the third part of this defense presentation, the same Al precursors previously studied are used to investigate the impact of precursor choice on nucleation and growth of dielectrics on the TMD, MoS2, by ALD. Even though the surface of MoS2 is chemically inert, it is shown that the precursor chemistry dramatically impacts the nucleation on the TMD. Using precursors with longer ligands results in enhanced coverage of the TMD, and this phenomenon is attributed to improved van der Waals dispersion interactions between the precursor and the TMD, facilitating better physisorption and thus nucleation. The resulting ALD films are used to create high-performance, top-gated MoS2-based transistors, and the study shows a direct correlation between precursor choice, nucleation quality, and device performance.

Together, these results offer key insights into how ALD processes can be engineered to address some of the challenges facing the semiconductor industry – providing a path forward towards continuing Moore’s law.

“Electrochemically Actuated Metasurfaces for Low-Power Nanophotonic and Energy Storage Devices ”

08.09.24  |  11:00AM |  044 Engineering Science Building

In an age of ubiquitous access to information, metamaterials offer a solution to a wide range of information display needs. Notably, metamaterial-based structural color promises vivid coloration across a broad color gamut, promising fade-resistance and a reduced environmental footprint. However, once structural parameters are set using traditional fabrication methods wavefront operations cannot be modified. In recent years, active elements have been incorporated into metasurface geometries to enable broader functionality controlled by an applied stimulus. In particular, electrochemical ion insertion allows for reversible carrier doping, volume expansion, and phase transition within the same system, and is an attractive actuation mechanism for a meta-optic platform. The research presented here aims to elucidate this platform by studying the use of electrochemical ion insertion and associated lattice modification to manipulate dielectric structural color within the visible spectrum. This study begins with amorphous silicon as a lithium-ion host material, due to its outstanding specific capacity and volumetric expansion during alloying. By designing a silicon structural color metasurface and monitoring its optical response in real time during ion insertion, we demonstrated continuous color bleaching and restoration while simultaneously establishing color resilience after irreversible capacity loss and energy storage ability. In contrast to silicon, anatase TiO2 offers ion hosting ability without associated volume expansion effects and reduced losses at visible frequencies, offering another attractive platform for electrochemically actuated structural color. Here, switching times were improved by minimizing diffusion distances and selecting H+ as a dopant for increased diffusivity in the material. The resulting device improved coloration time by an order of magnitude over actuation times for Li-ion insertion based active structural color. This dissertation demonstrates that electrochemical ion insertion is a viable method for dynamic structural color metasurface operation, and shows that improvement in color shifting, switching timescales, and energy storage ability are possible with the right host material, ion, and electromagnetic unit cell design.
