Examples of past master theses
Here you find three very good theses that I've supervised
Maren's thesis is an interview study on security debt conducted at a company. This is an excellent thesis conducting qualitative research, top grade.
Vilde's thesis is a great example of a well-conducted Design Science Research thesis, focused on developing visualizations of technical debt.
Oskar and Jørgen's master thesis is a great example of a design science thesis done in collaboration by two students to extend a machine learning platform. Well written, solid methodology and interesting results.
Daniel's thesis is a great example of how to apply Machine Learning to software engineering. It's a quite technical thesis (less well written than the other two) but the results have the potential to be ground-breaking
