I am a postdoc in theoretical computer science, at Harvard and MIT.
My hosts are Boaz Barak, Jon Kelner, Ankur Moitra, and Pablo Parrilo.
During Fall 2017, I was the Google Research Fellow in the Simons Institute program on Discrete and Continuous Optimization.
I am freshly graduated from a PhD in the U.C. Berkeley
Theory Group, where I was advised by
Prasad Raghavendra and
I got my B.S. in CS/Math from
Harvey Mudd College,
where Ran Libeskind-Hadas kept me out of trouble.
My research interests include Spectral Algorithms, Spectral Graph Theory, Approximation Algorithms, Semidefinite Programming (especially the Sum-of-Squares Hierarchy), Random Matrices, and more.
Here is a tutorial for pronouncing my name.
Check out the "Intro to sum-of-squares" blog post I wrote for Learning With Errors, Preetum Nakkiran's blog.
