About Me

I am an Associate Professor of Computer Science at the George Washington University. I have broad research interests, primarily in the area of computer security/cybersecurity, privacy, and usable security. Recently, I have been focusing on human factors in mobile authentication and oblivious access in the cloud.

I am the lead for the George Washington University/Usable Security and Privacy Lab (gwusec). If you are interested in joining the lab or collaborating on research, more information can be found there.
