I'm a beginning Master's student in Mathematics, I'm passionate about Mathematical Analysis and want to have my Master's thesis on some topic in Mathematical Analysis. Problem is, in my Department, the professors who work in this area are very few and they have a bad reputation. On the other hand, professors who work in Computational Mathematics and Numerical Optimization are more active in research and have a good reputation. I can't really decide whether is it more important to choose a potential supervisor and learn from him the elements of research in a research topic I'm not interested in or should I take the risk and stick to the topic I'm passionate about?. If I chose the research area which I'm passionate about there's a huge probability that my supervisor will not offer any guidance at all or even any interest in reading my thesis. I understand that the question is rather subjective as it depends on the personality of the student in the end. However, I'm looking forward to hearing other's analysis on the situation and if anyone had a similar experience or a challenge like this and how did they end up doing?
Thank you all for your time reading my post.
