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 taught CS 229r: Spectral Graph Theory in Computer Science.

I will not be holding office hours during Harvard's Winter Recess (Dec. 19 – January 3, 2020). My January and Spring Semester offers are still TBD. If you need to meet at a time outside of office hours, please contact my faculty coordinator Allison Choat <achoat@seas.harvard.edu>.

My 2012 monograph on Pseudorandomness is on my former website.
