I am in my 4rth year and finished my candidacy recently. I am very interested in my research and it is going forward at a decent pace. However, my advisor is giving me some trouble.
He is usually absent at the weekly research meetings which along with me includes a post-doc, a graduate student in his 6th year, and an associate professor from a different university. Even in the meetings he attends he hardly gives any suggestions or talks about any new ideas. He even fails to respond to some emails that I send asking him questions or general help.
I previously thought all this might be because he is the head of the experiment that we are working on, so he has little time to spare. But, now that I finished my candidacy I expect him to get more involved in my research. It's been a month since my candidacy and that has not been the case.
I think it is not too late for me to change gears and join a different group in the same field. Is this a fair thing to do? What other things should I consider before I confirm to switch.
