From 2012 to 2014, I was the Simons Postdoctoral Fellow with the Theory of Computation group of the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT. I completed my Ph.D. with Ryan O'Donnell at Carnegie Mellon University in 2012.

My research is in theoretical computer science with an emphasis on the complexity of boolean functions and sublinear time algorithms. I am particularly interested in the interplay between computer science, combinatorics, and information theory.
