Your advisors and mentors are valuable resources during this process. Schedule meetings to discuss potential dissertation topics and get their input. They can provide insights into the feasibility and significance of different topics.

Take into account the expertise of your advisors and mentors. Choosing a topic that aligns with their areas of knowledge can be beneficial, as they can offer guidance and support throughout your research.
