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 healthcare IT systems. I am Director of the IoT Security Lab at Johns Hopkins. I also founded Harbor Labs, a company that focuses on security for medical devices as well as consulting, technical expertise, and testimony in high tech litigation.

I am a frequent speaker on Information Security. Some highlights include TED talks (featured on the TED Radio Hour) in October, 2011 and September, 2015 about hacking devices, a TED Youth talk, testimony in Congressional hearings, and a high level security briefing at the Pentagon to the Assistant Secretary of the Army and a group of generals.

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. 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.

I am an avid poker player, and I participated in a TV show called Poker Night in America where I had the opportunity to play in a high stakes (for me) cash game against some of the top pros. I’ve also played in the World Series of Poker Main Event, but you know I did not win it, since I am still working my day job. My Intersession 2020 course at Johns Hopkins, Introduction to the Theory and Practice of Poker had 232 registered students and 14 auditing students. Videos of the lectures and slides are available online. I am also a columnist for 888 Poker, where I write a monthly column about poker strategy.

And finally, in April, 2018, I became a licensed Merchant Marine Master 100 Ton Boat Captain with Sailing Endorsement. Being on the water is my passion and my backup career if Computer Science somehow becomes irrelevant in the world.
