I have an extremely hard time deciding between two universities for my CS PhD. First of all, I'd like to say that right now, I'm more interested in working in the industry after my PhD, than in academia. Of course I would like to have a job that requires "PhD-level" work (for example, some research lab). I realize that in 5-6 years, my interests and desires can change quite a bit, but right now I'm more industry-oriented. Another thing worth noting is that I don't have a clear-cut research interest yet. I'm interested in a lot of areas, but if I had to choose my PhD topic right now, I would have an extremely hard time. So I can't choose my university based on perfect advisor matches. The two universities I can't decide between are Georgia tech and U of Chicago. My dilemma is mostly caused by the differences in reputation and faculty size. Georgia Tech is ranked top10 in CS, and has a very large faculty, while UofC is ranked top10 overall, but is well below the top10 in CS (but still has a pretty good ranking), and also has a smaller faculty. This would imply that GaTech is the better choice. However, in everything else, I consider UofC to be better (city, housing, funding, atmosphere). The number of faculty I share interests with is kinda proportional to the faculty sizes. I feel that I would have a larger number of choices at GaTech, but it is also true that it is enough to have 1 or 2 professors with whom I work with. So after choosing my advisor, having another 200 faculty members around is "useless" to me. So I don't know if a bigger faculty is actually that much better. I have looked at many professors at both universities, and there are multiple people at both universities with whom I'd gladly work with. So there are many potentially good matches at both universities, but obviously more at GaTech, simply because of the very large faculty there. I'll try to summarize the questions I'm most interested in: 1. How important is ranking? Do I miss out on something big if I don't choose the top10 ranked univ in CS (gatech)? For example during a CS-related job application, would a GaTech PHD be significantly better? How does the extremely good overall ranking of UofC come into this picture? Is it "useless" to me that UofC is ranked as a top10 university in the world? 2. Do I make a bad choice by seriously limiting the number of potential advisors by choosing a smaller faculty? I realize that this might be a stupid question (because it depends so much on my individual preferences and ability to choose an advisor), but I'd gladly hear anyone's personal opinion on this, or some personal experience from people who went to smaller CS departments without clear-cut research topics. But apart from these questions, I'm really interested in any kind of input on any of these 2 universities, or any advice from people who were in similar situations, or just any advice overall Many thanks in advance!
