I’m an Assistant Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee, Knoxville. I received my Ph.D. in Computer Science from the University of Maryland, College Park in May 2020 where I worked with Prof. Tudor Dumitras.
My research interests include computer security (data-driven security and usable security) and computer networks (Internet measurement). I am interested in identifying the root causes of security threats by understanding actors (e.g., adversary and end-users) involved, with data-driven and human-centered perspectives (i.e., usability study).
I have been awarded the 5th annual NSA Best Scientific Cybersecurity Paper (2017) and the Ann G. Wylie Dissertation Fellowship (2019). My works about the Code-Signing PKI have been featured in Ars Technica, The Register, Schneier on Security, Threatpost, etc.
I am actively looking for self-motivated students! Please email me if you’re interested in security and computer networks.
