About Me

I'm a postdoc at Carnegie Mellon University, hosted by Elaine Shi. Previously I completed my PhD at University of Washington advised by Rachel Lin and Stefano Tessaro. My primary research interest lies in cryptography.

I obtained my bachelor's degree from University of California, Los Angeles, and my master's degree from Carnegie Mellon University.
