Some tips for coming up with a thesis topic are to ensure the topic is novel, set the topic in an already existing field of research, and make the topic something that can be executed well and completely. Consult with professors or counselors about the topic for guidance.
A novel thesis topic can be focused on finding a novel outcome or using a new methodology to come up with that outcome. Placing the thesis topic in an already existing field of research helps to justify why the thesis topic matters and how the outcome can be applied. Choose a topic that can be completed using available resources to demonstrate the accessibility and feasibility of the topic.
