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 spring I am teaching CS 208.

My regular Spring-semester office hours are Mondays, 1:30-2:30pm ET, via Zoom, and Thursdays, 2-3pm ET, in my office. Updates and schedule adjustments to those hours will also be posted in "Upcoming Events", below. If you need to meet at a time outside of office hours, please contact my faculty coordinator Allison Choat <achoat@g.harvard.edu>.

My 2012 monograph on Pseudorandomness is on my former website.
