Teaching
I teach in the Department of Computer Science at Georgetown, mostly in security and networking.
Current course materials live on Georgetown Canvas and are available to enrolled students. If you are a Georgetown student deciding whether a course is right for you, please email me.

Advising
I supervise Ph.D. students, postdoctoral fellows, master’s students, and undergraduate students; current and former advisees are listed on the students page. I have also supervised independent studies (“tutorials”, in Georgetown-speak) — if you have a security project you want to pursue and have taken the relevant coursework, please contact me.
Prospective Ph.D. applicants should read the notes for applicants before writing to me.
