I finished my masters last spring and will be starting the doctoral program in the same department this fall, however, I don’t want to work with the same advisor who directed my masters. There were some definite personality issues there, and their research interests do not align with my own. I’ve identified another professor who has research interests similar to my own, and who has expressed in the past a willingness to work with me. How do I make the change while causing as little drama as possible?
