Luckily I got in academia after having a serious conflict with my previous advisor. The problem was that he gave my dissertation proposal to his previous student (another his previous student said that he loved her a lot). She even got $100,000 NSF grant with the proposal.
I said it was unfair. Then he did his best to kick me out of the school (he even called the police for the reason I was shown up in his office; contacted all people to say that I am not qualified for a Ph.D. and so should be kicked out).
A school dean saved me and so I graduated. However, for the conflict, I couldn't get in my field (I am in totally different field); still I need to take medicine to get in a sleep, to meet people and to control my anger.
Anyway, I'd like to go back to my own field again because it is too tough to struggle in a new field. Any advise? Also I'd really like to pay all back to him regarding what he did to me. What could be the best way?
Anyway, he is a full professor in a well-known research school; also he is a big name and so about 30% of faculties in this field are his previous students & 50% of senior faculties are his good friends.
