Maybe, the question itself sounds really stupid to some of you guys, like, "what...? of course UPenn you idiot!"
But my research topic is gravitational weak-lensing and all the three schools have top-class lensing programs.
*UC Davis: the biggest lensing resources, good weather in northern Cal. and 23,500$ funding
*Brown: small but concentrated program, the stipend is over 31,000$
*UPenn: the most name-valued one, lensing program is also great. 29,000$ stipend
I almost made up my mind with UPenn but I am not totally sure.
What do you think, guys?
