I study the security of computer systems. I try to understand why it seems difficult to build secure systems and how we can get better at it.

I also have an interest in innovative approaches to information security education. I like taking systems apart and understanding how they really work to discover and fix vulnerabilities in software. I mainly work on cooperative security: the challenge of getting security systems to work together (particularly in complex network environments) to respond to attacks and interactive security analysis: the challenge of supporting cooperative analysis of large, opaque artifacts.
