Welcome!

I am a computer security research scientist and a principal investigator at the U.S. Naval Research Laboratory. I am currently focused on conducting research in the area of computer security, with a particular interest in the security and privacy of distributed computer systems.

I communicate research findings by publishing peer-reviewed research articles and presenting them at research conferences. This site presents a summary of my scholarly activity and an archive of my research outputs.
