I'm an Assistant Professor at University of Virginia. My research focuses on developing novel technologies for the security, privacy, and safety of modern and emerging systems. I analyze and model systems, drawing on program analysis, protocol analysis, machine learning, and human factors to understand the risks and develop systems that are secure and privacy-preserving.
 
My work has been published in top-tier security conferences (such as Oakland, CCS, Usenix Security, and NDSS), and my work has generated real-world impact as countermeasures and design changes directly resulting from my research have been integrated into platforms (such as Android, Chrome, Firefox, and iOS).
 
Before joining UVa, I was a Ph.D. student at Carnegie Mellon University. I am fortunate to be advised by Professor Patrick Tague. I interned at Microsoft Research (with Dr. Cormac Herley and Dr. Stuart Schechter), Facebook (with Security Infrastructure team), and Samsung Research (with Dr. Peng Ning).
 
Looking for motivated students! Please don't hesitate to email me if you are interested in my research. I'm looking for passionate and smart students to drive my projects.
