New: I am on sabbatical during the Spring 2018 semester (returning Summer 2018). I will have regular access to email, but will check my voicemail only periodically almost never.


Research Interests

My academic interests include privacy-preserving technologies, e-voting security, eavesdropping and wiretap systems, operating system security, network and protocol security, and network intrusion detection.

Basically, I like breaking stuff and occasionally fixing things.

I am the director of the Georgetown Institute for Information Assurance and co-direct the CS SecurityLab.

A more formal biography is also available.
