I am a member of Harvard's Theory of Computation research group.  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 an office hour on Wednesdays, 4:00-5:00pm. Please note that my office hour may be 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>.
