Paso, The department admitted you so now has an obligation to find faculty for you. If you don't get some news this week, I would pick up the phone, get the graduate chair in the department (the faculty member, not the adminstrator) on the phone and tell him/her your story to indicate - politely - that they are about to put you in a terrible position and must take responsibility for this. You must be active in this and you have a right to be active in this. You should start trolling their website and the university website to start identifying people you could work with so that if they say "Oh, we're still looking..." you can respond: "I am going to email Dr. Smith and ask if he can serve as my new advisor since I need this settled right away." Is it a big program? Their may be a few other people who can stand in for the prof that has flaked out on you. It is always a good idea to apply to a program where you have lots of supervisory options since this can happen in any department if faculty are bad at saying "no" when asked about supervision, or go on sabbatical and refuse to work with grad students (I work with grad students all the time, sabbatical or not), or if someone becomes gravely ill unexpectedly. I switched grad advisors during my PhD and I know quite a few people who had to change (out of duress like you) and landed on their feet just fine. The main thing - don't be passive. University culture often thrives on students who don't stand up for themselves... P.S. Hang in there, you and your spouse will probably be just fine. - Prof. Susan
