Penn State vs. Georgia Tech for numerical relativity

[geekusprimus]

Hi, everyone,

I recently got accepted to both Penn State and Georgia Tech for a PhD in physics. I have yet to visit the schools, so I'm certainly not basing my decision on what anyone here says alone.

My interests are in numerical relativity. Now, Penn State is probably a stronger school overall for gravitation, but the faculty member there doing numerical relativity, David Radice, is brand new and just barely finished a postdoc (read: probably hasn't earned tenure yet). Georgia Tech, on the other hand, has a large gravity group with some very prominent faculty in numerical relativity. Their rankings in physics overall are pretty comparable according to the US News (#25 vs #28), and they're both offering me pretty generous stipends.

What do any of you know about these schools and their physics departments?
