How to Find the Best Dissertation Topic: A Guide for Doctoral Students

This article has been a long time coming. I typically write about leadership and contextual intelligence. But as someone who has earned two PhD’s and has been advising doctoral students for over a decade, I know the pain of developing the perfect dissertation can be real! So I put together a few of my thoughts and common advice that I give to my own doctoral students here for you.

There is no question about it that choosing a dissertation topic can feel overwhelming. It’s a decision that seems to carry immense weight, as your topic will shape not only your research but potentially your academic career. Many PhD students find themselves stuck in this stage, uncertain of where to begin or how to find a topic that is both interesting and feasible.

But here’s the truth: finding a dissertation topic doesn’t have to be paralyzing. I can walk you through practical steps to help you find a great dissertation topic and debunk some common myths and mistakes along the way.

Common Mistakes to Avoid When Choosing a Topic

1. Picking a topic that’s too broad or too narrow Many students either choose a topic so broad that it’s impossible to tackle in the time they have, or so narrow that there’s little research or resources available to support their work. A dissertation topic should strike a balance — it must be specific enough to allow in-depth research but broad enough to find sufficient academic material.

2. Choosing a topic you think you “should” do Some students choose topics based on what they think will impress their committee, future employers, or align with current trends. While it’s important to consider academic trends, choosing a topic purely for external validation can lead to burnout. Pick a topic that genuinely interests you — one that aligns with both your personal passion and career goals.

3. Failing to do enough preliminary research Before committing to a topic, it’s crucial to spend time reading recent papers, studies, and books in your field. Jumping into a topic without thoroughly exploring the existing literature can lead to frustration when you discover halfway through that there’s little to no research available to support your argument.

4. Ignoring the feasibility of the topic An ambitious topic may sound appealing, but consider whether you have the time, resources, and ability to complete the research. Some ideas, while intellectually exciting, may be logistically impossible to complete within the constraints of your program. Keep it feasible and always remember that the more ambitious projects can be done once you attain your first professional position.

Debunking Common Myths

Myth 1: I need to find a groundbreaking, never-before-researched topic. PhD students often believe they must come up with a completely original idea. While innovation is important, dissertations are often about adding to existing conversations, not starting entirely new ones. You can make a valuable contribution by building on previous work, applying existing theories in new contexts, or providing fresh perspectives on ongoing debates.

Myth 2: My dissertation topic must be my life’s passion. It’s tempting to think that you need to love your topic endlessly to finish your dissertation. However, passion fluctuates over time. A more realistic goal is to choose a topic that sustains your curiosity and keeps you engaged, even during the difficult phases of research and writing.

Myth 3: I must be 100% certain about my topic before I start. You don’t need to have every detail figured out before you begin. In fact, many students refine and adjust their topics as they delve deeper into the research. Your initial idea is just a starting point — allow yourself the flexibility to evolve your focus as new insights emerge.

Frequently Asked Questions About Choosing a Dissertation Topic

Q: How can I ensure my topic is feasible? Before finalizing your topic, ask yourself: Does it align with your program’s timeline? Can you access the necessary data, resources, or tools? Have other researchers successfully explored this area, and is there room for your contribution? Discuss your ideas with your advisor to gain clarity on feasibility.

Q: What if someone else has already researched my topic? If someone else has already researched your topic, that doesn’t mean your idea is invalid. Consider how you can add a new perspective, test their findings in a different context, or fill in gaps they left behind. Academic research is about contributing to an ongoing dialogue, not being the sole voice.

Q: How do I know if my topic will sustain my interest? Spend some time exploring your potential topics. Dive into the literature, attend conferences or webinars on the subject, and talk to other academics in the field. If you find yourself excited and curious about these discussions, it’s a good sign that the topic will hold your interest over time.

Limiting Beliefs You Need to Let Go Of

Belief 1: I’m not smart enough to find an original topic. This imposter syndrome creeps into the minds of many PhD students — including myself. Remember, your goal isn’t necessarily to find the most unique topic in the world — it’s to make a contribution to your field that’s meaningful, rigorous, and well-supported.

Belief 2: I don’t have enough time to choose the right topic. Choosing a dissertation topic requires time, but it’s time well-spent. Rushing into a decision can lead to bigger setbacks down the road. Give yourself permission to explore your options thoroughly before committing.

Belief 3: If I change my topic later, I’ve failed. Research is a process of discovery — let me say that again… “It’s a process.” My favorite word to my doctoral students is “iteration.” A good dissertation is a series of iterations. If your initial idea shifts as you learn more, that’s a natural part of the journey. Changing direction doesn’t mean failure — it means you’re refining your work based on new knowledge.

Challenges to Implementation

One of the biggest challenges PhD students face when choosing a topic is decision paralysis. With so many options available, it’s easy to get stuck in the process of overthinking and second-guessing. To overcome this, break down the decision-making process into smaller steps:

1. Brainstorm several areas of interest.
2. Research what’s been done in each area.
3. Narrow down your focus by identifying gaps or areas for further exploration.
4. Talk to your advisor or peers to get feedback on your ideas.

Remember, the goal isn’t to find the “perfect” topic but a feasible and engaging one.

One Key Strategy You Can Implement Today

If you’re struggling to find a dissertation topic, try this exercise: Write down three areas of research that genuinely interest you. Then, spend 30 minutes reading recent papers or articles in those areas. Take note of any gaps, questions, or debates that arise. By the end of the exercise, you’ll have a clearer sense of where your interest lies and what’s already been explored.

Final Thoughts

Choosing a dissertation topic is a significant milestone, but it’s also an opportunity to explore your passions, contribute to your field, and set yourself up for future success. Be patient with yourself, embrace the process, and don’t be afraid to ask for guidance along the way.

Remember, the perfect topic is one that challenges and excites you — not one that leaves you feeling paralyzed by the weight of the decision.
