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. 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.

Interested in having me as a mentor for your PhD?

Undergrad or masters student at GW interested in research?

Want to meet with me?

Am I listed as your MS Academic Advisor?
