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 will teach CS 120: Intro to Algorithms and Their Limitations.

My regular office hours for Fall 2021 are Mondays, 1:30-2:30pm ET (via Zoom) and Thursdays, 11:15am-12:15pm ET (in person). See the "Upcoming Events" below for ad-hoc office hours, as well as 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.
