About Me

I am a Ph.D. student in the Yale Applied Cryptography Lab, working with Ben Fisch. My current research focuses on recursive zero-knowledge proofs, which have powerful applications in decentralized systems and machine learning.

I received a B.S. and M.S. in Computer Science from Stanford University. I worked with Fei-Fei Li and Serena Yeung in the Stanford Vision and Learning Lab.

At Pinterest, I have led a variety of large-scale machine learning projects and published research on representation learning, object detection, and recommender systems.

I was the co-founder and CTO of Reveal, a venture-backed startup that developed one of the first social networking apps with cryptocurrency incentive mechanisms.
