I am a PhD student at MIT. I am fortunate to be advised by Pablo Parrilo. My research is supported by an NSF PhD fellowship and a TwoSigma PhD fellowship.
Previously, I was an undergrad at Princeton under the wonderful supervision of Elad Hazan and Emmanuel Abbe. I spent two of my undergrad summers interning in tech (at Google/Google Research) and the other two on Wall Street (DE Shaw and Tower Research).
In my free time, I like to play chess. I obtained an International Master norm in Spain in 2015.
