I am an Assistant Professor at the University of Illinois at Urbana-Champaign, where I lead the Secure & Transparent Systems Laboratory. My research confronts a broad array of issues in computer security. I am especially interested in the challenges of detecting, investigating, and preventing intrusions in various computing environments such as operating systems, organizations, cloud computing, and the Internet of Things. Increasingly, my work investigates and addresses the concerns of the users that interact with these systems.

I received my Ph.D. from the University of Florida, where I was advised by Professor Kevin Butler and a founding graduate student of the Florida Institute for Cybersecurity. My dissertation work was in the area of data provenance, particularly the construction of secure provenance-aware systems. I obtained my M.Sc in Computer Science at the University of Oregon, and bachelors degrees in Computer Science and English Literature from the University of Maryland.

Wow! Our systematization of knowledge paper on data provenance, "History is a Vast Early Warning System: Auditing the Provenance of System Intrusions," has been accepted to the IEEE Symposium on Security and Privacy (Oakland'23)! This one has been in the works for about as long as our lab has been inexistence, with many students taking turns carrying the ball. Congrats to lab members Muhammad Adil Inam, Yinfang Chen, Akul Goyal, Jason Liu, Jaron Mink, Noor Michael, Sneha Gaur, and Wajih Ul Hassan!
