I am an Associate Professor of Computer Science at Brown University. Before joining Brown, I was a researcher at Microsoft Research (Redmond Lab).

My research is in cryptography and is driven by real-world problems from privacy, security and surveillance. My primary focus is on the design and cryptanalysis of encrypted algorithms, which are efficient algorithms that operate on end-to-end encrypted data. I maintain interests in various aspects of theory and systems, including applied and theoretical cryptography, data structures and algorithms, data systems, algorithmic fairness, game theory and technology policy.

I direct the Encrypted Systems Lab and am a member of the CAPS group.
