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 one regular weekly office hour. The Spring semester office hour time is still being determined, but should be posted shortly. 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>.

See FAQ with answers to common inquiries (including reference letters, graduate admissions, advising, internal and external service, appointments, and refereeing) and information on contacting me.
