I feel strongly that security solutions must be balanced with usability; that security in the real world is largely about making good trade-offs and balancing risks. Therefore my work has mostly focused on concrete problems in computer security and building tools that can be used in the real world. This site collects  together all of my research and development work in applied security done both as a student and at the NCSA where I started working as a security engineer in 2003.

Currently, I am a Sr. Security Engineer and CISSP working on several projects that blend research and application. While much of my early research focused upon privacy and data sanitization, currently I am focused most on network security and traffic analysis, risk analysis, developing security plans and policies, and law enforcement applications of cyber-security.
