How to "find" good people in a field? So I'm a 3rd year student, not quite at the stage to be applying for grad school, but almost there. I'm trying to get a preliminary idea about where I'd like to go/apply to. From what I've gathered, of course it's great to go to a "top ranked" school (according to the internet rankings anyway), but it's better to go to a school that is good in your intended area, as if it's a "good" school, but no one there does what you wanna study, there's a good chance of not being admitted since you'd essentially be on your own. So I'd like to know of a process to find out who's good in a particular area. I'm going to be applying for pure math, but just generally speaking, how does one determine "it'd be better to go to X for algebra since they person Y, or don't go to school Z because although they have people in algebra, they don't publish much" or something along those lines. All I have to work with right now are things like US-news rankings and what not, but I somehow feel like those aren't complete trustworthy all the time. Any advice? Sorry if I come off misinformed - I very well might be. But it just seems like a lot of forums, people, etc. just talk about the "top ranked" schools, and I'd like a different perspective.
