About

Hi! I am a CS Ph.D. student in the UC Berkeley RISE Lab, where I am co-advised by Raluca Ada Popa and Alessandro Chiesa. My recent research interests are applied cryptography, decentralized systems, and zero-knowledge proofs.

I received my Bachelor's degree at Shanghai Jiao Tong University in 2017, where I was a member of the ACM Honored Class.

I am a co-author of arkworks, an ecosystem for developing and programming with zkSNARKs.
