I'm a postdoc researcher working with Micah Sherr at Georgetown University. Check out the Georgetown SecLab!
Previously I was a computer scientist in the formal methods section of the US Naval Research Laboratory. I worked a lot with Aaron Johnson, Rob Jansen, and Paul Syverson on network traffic analysis.
I research computer network privacy and security. Recently, I've been working on covert network communication protocols. I've also worked on topics including high-performance network simulation, secure statistics in distributed systems, and path selection in low-latency anonymity systems.
