I have moved to a new position as Associate Professor of Computer and Information Science and Engineering at the University of Florida (click here for my new web page) but I maintain a courtesy affiliation within the CIS department at the University of Oregon and am happy to continue to advise and help students here.

My research focuses on security issues as they relate to storage systems, large-scale systems architectures, and networks. Recent work in my group has included understanding the security of portable storage and the USB interface, mobile phone security, and attacks and defenses against the cloud infrastructure. Some of my other research areas of interest include security in interdomain routing, propagation of malicious code through the Internet, applied cryptosystems, and using secure hardware to enforce systems security. I formerly directed the OSIRIS Lab at the University of Oregon and am currently co-director of the SENSEI Center at the University of Florida.
