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.

This semester, I am teaching Computer Science 208: Applied Privacy for Data Science. Class meets Monday/ Friday 10:30-11:45 AM. 

My regular office hours this spring are Tuesdays 2-3 PM and Thursdays 10-11 AM. Please note that these hours may be subject to change due to fluctuations in my weekly schedule – 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>.
