About

I am a first year PhD student at MIT. I am fortunate to be advised by Pablo Parrilo. My current research interests are at the intersection of convex optimization and (randomized) approximation algorithms. I am supported by an NSF GRFP grant.

Previously, I completed my undergrad at Princeton University (class of '16) under the wonderful supervision of Elad Hazan and Emmanuel Abbe. I spent 2 of my undergrad summers interning in tech (at Google/Google Research) and the other 2 summers interning on Wall Street (DE Shaw and Tower Research Capital).

In my free time, I like to play chess. I obtained an International Master norm in Spain in 2015.
