1) Top ranked university, with 1 professor i LOVED, but have since heard she's crazy. didn't like a lot of others' research there, although we got along fine. in california ! which is where I thought I wanted to go.
2) Highly respected institution, with a few professors whose research I'm interested in, but didn't get to meet all of them on my visit. one professor i met there with is brand new and we got along great - also he's very heavily recruiting me. i'm nervous about the fact that he's so new though... No idea how he'd be as an advisor since there aren't any grad students to ask. no TAing. in california also.
3) Top ten university, with 2 professors that I got along with great, 1 whose research I'm actually interested in, but one who I'm not. the one whose research I thought was pretty cool is heavily recruiting me (lots of emails) which makes me feel special. in NYC. (which could be cool, but I did want to go west coast, or so I thought)
Money's about the same at all of them, so that's not an issue... All of them have good placement.
Basically I have one professor at each school that I'm interested in.. How do I pick?
PS. The reason I only have one is because at first I thought I was interested in one sub-division of chemistry (synthesis), that I now am not interested in, so when I went on these visits, I met with tons of people in that field, rather than the one I'm interested in now (chemical biology).
