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 am teaching CS 229r: Spectral Graph Theory in Computer Science.

My regular fall office hours (via Zoom) are Mondays 12:30-1:30pm ET, and Thursdays 9:00-10:00am ET. Please note these hours are subject to change; see the calendar below for updates. If you need to meet at a time outside of office hours, please contact my faculty coordinator Allison Choat <achoat@seas.harvard.edu>.
