I am a member of Harvard's Theory of Computation research group and also lead Harvard's Privacy Tools Project.  My research areas include computational complexity, cryptography, randomness in computation, and data privacy. This fall I taught CS 229r: Spectral Graph Theory in Computer Science.

My regular office hours for Spring 2021 are Mondays 12:30-1:30 and Thursdays 11-12 (Eastern time). See the "Upcoming Events" below for any changes and zoom links. If you need to meet at a time outside of office hours, please contact my faculty coordinator Allison Choat <achoat@seas.harvard.edu>.

My 2012 monograph on Pseudorandomness is on my former website.
