# Ritvik Ramkumar

I am currently a sixth-year PhD student at UC Berkeley in the Department of Mathematics. My advisor is David Eisenbud and I am primarily interested in Algebraic Geometry (with a view toward Commutative Algebra). Prior to that, I was an undergraduate student at the University of Waterloo.

Starting in the fall, I will be an H. C. Wang Assistant Professor at Cornell University in the Department of Mathematics.
