May be I can talk to DGS as you said. I was also planing to talk someone in the department that may access to the potential advisor. Thanks for the reply.

Hi, I want to change my current phd subject/advisor. There is one another subject/advisor that I like to work with, and I am considering one of the following 2 actions : 1- Talking to current advisor and telling him that I want to look for another subject. Then talking to the other one. 2- Talk to new potential advisor in private. If both of us seems that we may work together on a subject, then talk to current advisor. Otherwise continue with the current one. If I follow first action and if, for some reason, fail to work with the new guy, then I would loose both, and I don't think there is another subject/advisor that I can work with. For the second action, I am not sure how it seems from the point of view of US academic work ethic. I like to hear any thoughts, thanks in advance.
