Welcome. I am an Associate Professor of Computer Science and Engineering at Penn State University. I co-direct the Systems and Internet Infrastructure Security Lab (SIIS Lab) with Prof. Patrick McDaniel. The SIIS Lab is part of the Network and Security Research Center.

My main research area is computer security. I am interested in tools and techniques to enable developers to build higher (measurable) integrity computer systems. Specifically, I am interested in virtual machine systems, Linux security, source code analysis, connecting programming language security to the rest of the world, and access control systems.
