I am a third-year PhD student at a US institution. I have been thinking of changing my research group basically for two reasons: 1) my research interests have become quite different from the interests of people within the group and 2) members of the group are working online so there is no way I can meet anyone in person. I have seen that my friends are able to meet with their advisors regularly in person to discuss research while I haven't been able to do so.
I've talked with my advisor about this and he basically told me that one has to be flexible and work on things even if he is not interested in them. I talked with a few other professors and they are only interested in taking incoming students, not students switching from other groups. My question is whether my advisor's advice (to be flexible and work on research one might not be interested in) is a sound advice. Also, I got a feeling that trying to switch out from my research group suggests failure and this will make potential new advisors hesitant to take me. I think I can seek advice from the head of the department on how to proceed with the switch, but I do not want to be in a situation in which I can't find new advisor and the only option left is to leave the program. Any advice will be appreciated.
