I am Professor of Computer Science at Johns Hopkins University and Technical Director of the JHU Information Security Institute. My primary research area is Computer Security, and my latest research focuses on security for electronic medical records. I am the Director of the Health and Medical Security (HMS) Lab at Johns Hopkins. I also founded Harbor Labs, a company that provides technical expertise and testimony in high tech litigation.

Prior to joining the faculty at Johns Hopkins, I worked in the Secure Systems Research Department at AT&T Labs - Research. My work there was in the area of cryptography, network security, Web security and secure Internet services. Before AT&T, I worked at Bellcore (now Telcordia) in Applied Research. I received my B.S. (‘89), M.S.E. (‘91), and Ph.D. (‘94) in Computer Science from the University of Michigan in Ann Arbor.

My favorite hobby is playing with my kids. After that is sailing with my family, playing soccer, tennis, and poker. I enjoy golf too, especially all that hiking in the woods I get to do looking for my ball. I'm pretty much a sports nut and will play or watch just about anything, especially Michigan sports. I like to play the piano, and if nobody is around, I sometimes sing. If people are around, once they hear me sing, usually pretty soon, there's nobody around, so it works well. I used to be into chess, and I could probably get into it again, if I ever find the time, and a chess partner who I can beat on a regular basis. I don't enjoy losing. I exercise almost every day, and I just don't feel the same if I can't do something active.
