My research and outreach efforts are mostly focused on child rescue (thwarting internet-based child sexual exploitation), an important nonpartisan issue. More broadly, I work in the areas of security, privacy, and forensics applied to networking.

I have been named an ACM Fellow "For contributions to network forensics, security, and privacy, and for thwarting crimes against children".

You can see a list of all of my publications online. More information can be found on the UMass Amherst Rescue Lab website.

I am the founding Director of the UMass Amherst Cybersecurity Institute. And I am Co-Director of the UMass Accelerator for Responsible Technology, which transitions research into practice.




I am passionate about drawing attention to the harms to children that take place on Tor (and Freenet) and on mobile apps. Visit my sites focused on

  • the dangers to children on Tor and the blind eyes of academia; and
  • the dangers to children on mobile apps.
  • Or watch the invited talk I gave at Usenix Security on Tor and child sexual exploitation. I gave the talk in 2019 and sadly not a thing has changed.

      Because exploitation knows no borders, I work with partners and collaborators in the US and around the world, including Oak Foundation, Safe Online, the Canadian Centre for Child Protection, and the Bright Initiative. See my full list of sponsors and collaborators on the Rescue Lab web page.
