I am an Assistant Professor in the Department of Computer Science at Brown University. I am honored to be part of Brown's Theory Group.
I received my Ph.D. from UC Berkeley in 2019 under the supervision of Sanjam Garg and my BS degree from ACM Honors Class at Shanghai Jiao Tong University. I am a recipient of the NSF CAREER Award, Meta Research Award, Google Research Scholar Award, and Amazon Research Award. Here is my CV. My research interests lie broadly in cryptography and security, with a focus on secure multi-party computation (both theoretical and applied).
For Brown students: If you are interested in learning more about cryptography research, you are welcome to attend our crypto reading group. Subscribe to the crypto mailing list here for announcements!
