I am a graduate student in the U.C. Berkeley Theory Group advised by Prasad Raghavendra. Prior to coming to Berkeley I got my B.S. in Math and M.S. in Computer Science from Stanford.

I am interested in the complexity of constraint satisfaction problems, approximation algorithms, hardness of approximation and spectral graph theory among other things.
