about me

I am an assistant professor in MIT's EECS department and am a member of CSAIL. My research focuses on computer security, cryptography, and computer systems.


research

I build systems that use cryptography to empower and protect their users. The projects that excite me the most: (1) serve the interests of the end user, (2) provide strong and precise forms of security, often using new cryptographic ideas, and (3) have impact through real-world deployment.

  • New techniques for reducing the computational cost of private information retrieval
  • Prio, a system for the privacy-preserving collection of aggregate statistics (Mozilla's Firefox browser uses Prio for its pilot privacy-preserving telemetry system.)
  • True2F, a system for token-based two-factor authentication that protects against a wide class of hardware faults and backdoors
  • The study of preprocessing attacks on cryptographic primitives and the risks they pose to our standardized primitives, such as the AES block cipher and the NIST family of elliptic curves


activities

I have served on the program committee of Oakland 2021, CRYPTO 2020, Oakland 2020, and CCS 2018.

A variety of organizations, including the National Science Foundation, the U.S. Department of Defense, and Facebook, have funded my research.


history

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