There are professors that I'd like to work with in both universities. There is one research group at Columbia I am very enthusiastic about, however, not many others coincide with my interests. On the other hand, I can think of working with many more groups at Cornell. How important is this -- having the possibilities? Also, professors from my uni state that Cornell has a stronger program for PChem. However, I don't know how would it be like to live in Ithaca. It seems kinda harsh, given the weather conditions and so on. What other factors should I consider while deciding? Any suggestions would be highly appreciated!
