I am a postdoctoral researcher at University of Maryland, hosted by Prof. Jonathan Katz.

I completed my Ph.D. at Cornell University under the supervision of Prof. Elaine Shi. During my doctoral study, I have been a visiting graduate student or an intern at Simons Institute, Yahoo! Labs, Bell Labs and IBM TJ Waston Research Center.

Research Interests: Cryptography, security and programming languages.
