About

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

My research spans the domains of cybersecurity and applied cryptography. I am interested in privacy, secure and verifiable computation, zero-knowledge proof, fuzzy cryptography, and trustworthy machine learning.
