Main Question or Discussion Point
I'm facing the question of choosing the right supervisor for my PhD in theoretical physics. On one hand, there are professors who are well-known and have done great work in their youth, but whose publication records in recent years are not great. On the other hand, there are young faculty members perceived as "rising stars" and are active researchers in currently popular topics. Which type of supervisors is a better choice, if I want to maximize my chance of getting job positions (if any :D) in academia after PhD?
