I am Professor of computer science at Johns Hopkins University. I teach courses in computer security and privacy. My primary research interest right now is the security of electronic voting, and I am the director of the NSF ACCURATE Center. I'm also an election judge in Baltimore County. Besides my faculty position, I am also the president and founder of a computer security consulting firm called Independent Security Evaluators. My hobbies are photography, soccer, tennis, sailing, golf, billiards, high tech gadgets, and playing with my kids.
