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.

I will be on sabbatical during the 2019-2020 academic year and will not be teaching any courses during that time. I will continue to be available for regular research meetings and will hold one regular weekly office hour. This hour is usually on Wednesdays 4:30-5:30, but please note that it is subject to change; see the calendar below for any relevant updates. If you need to meet at a time outside of office hours, please contact my faculty coordinator Allison Choat <achoat@seas.harvard.edu>.
