I am a fourth-year PhD student in computer science at Stanford advised by Dan Boneh.

The Applied Crypto Group is my academic home on campus, and I collaborate with folks from the Secure Computer Systems Group. If I am not in the Gates Building, you can find me out enjoying the hills.


My research uses cryptographic techniques to make provable privacy practical. My recent work includes the Riposte system for anonymous messaging at million-user scale, the Balloon hashing algorithm for secure password storage, and a scheme for generating cryptographic secrets on devices with poor sources of randomness.

An NSF Graduate Research Fellowship and an NDSEG Graduate Fellowship have funded me in part at Stanford.


I graduated from Yale University in 2010 with a B.S. in computer science. Before that, I was a student at Berkeley High School.
