I'm just finishing my third year of my graduate program at a top 30 school (between 20 and 30). I came here to work with a certain faculty member and have just been informed that he is leaving after this summer. I actually turned down a higher ranked school (ranked 15-20) to come here largely because of him and I feel deflated right now. He's currently the chair of my Master's committee (which is optional in my program), but i won't finish it until this summer or fall due to data access delays. I developed a good report with him and am currently funded on his NSF grant for this school year, which I hope will still result in publications. I'm just about to start my desertion work at the beginning of next year. I should mention that I am also working on a couple of other projects with highly regarded senior faculty, but I'm not nearly as close to them. I just feel so down about this, worried that I won't be able to get that R1 job I dream of. We are also losing another faculty member (didn't get tenure) in the same area of interest, which means that we have 1 faculty member who will be serving about 8 students. I was just curious if any one else had gone through something similar? Am I blowing things out of proportion? Is there any bright side to this?
