Professor
College of Information and Computer Sciences
University of Massachusetts Amherst

I work in the areas of security, privacy, and forensics applied to Internet and cellular networks. My research projects are currently funded by the NSF, the Department of Justice, and Operation Underground Railroad. We work in collaboration with the Internet Crimes Against Children Task Force, through which my group's work has had an international impact, including their rescue of more than 300 children from sexual abuse based on our tools. In the networking area, my work includes mobile networking, disruption tolerant networks, and peer-to-peer networking. My work on mobile networking has been funded by the NSF, NSF/GENI, and DARPA.

You can see a list of all of my publications online. More information can be found on the Center for Forensics website.

I am the founding Director of the UMass Amherst Cybersecurity Institute.
