I am a second-year PhD student in Computer Science at Stanford University. I am fortunate to be co-advised by Aviad Rubinstein and Moses Charikar. My CV is available here.
I graduated from Carnegie Mellon University with a B.S. and M.S. in Mathematical Sciences with a minor in Science, Technology and Society as a Knaster-McWilliams Scholar. While there, my advisor in the Honors Program was the truly excellent Venkatesan Guruswami.
My research interests lie in theoretical computer science, particularly in the application of algebraic and geometric techniques.
My most recent work has been in approximation algorithms and hardness of approximation, particularly for constraint satisfaction problems.
