I am an Associate 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.
