Assistant Professor


I am an Assistant Professor in the department of Computer Science at Virginia Tech. Prior to joining VT, I was a Postdoctoral Fellow hosted by Prof. Elaine Shi at Carnegie Mellon University (CMU), and a Research Associate hosted by Prof. Attila A. Yavuz at the University of South Florida (USF). I received my PhD degree from USF in August 2020.

My research spans the domains of applied cryptography and machine learning, with special interests in privacy-enhancing technologies. I am interested in zero-knowledge proofs, multi-party computation, oblivious RAM and searchable encryption.
