I joined the Department of Computer Science and Engineering at Penn State University in 2005. I am a part of the Systems and Internet Infrastructure Security (SIIS) Lab and the Networking and Security Research Center (NSRC), and am co-advised by Dr. Patrick McDaniel and Dr. Trent Jaeger.

Currently, I'm investigating interesting new uses for OS Virtualization technologies like Xen. I am primarily interested in the security issues of these new uses. Additionally, much of my work revolves around policy enforcement systems (such as SELinux) and how those systems apply to OS and virtualization technologies. See the HotSec paper in my publications section for more details. My other professional interests include network security and protocols.
