About Me

I'm currently pursuing my PhD degree in computer science in the area of systems/networking/security at the University of Illinois Urbana Champaign working with Nikita Borisov. In 2007, I received an MS degree in systems and networking at UCSD working with Amin Vahdat. I got a BS in computer science from Georgia Tech in 2004. While there I was an undergraduate research assistant for Wenke Lee. Since 2001, I have been employed at Los Alamos National Lab where I work as a security researcher.

My areas of research include covert communications, system and network forensics, and traffic analysis. While at UCSD I worked on a project called Glavlit which is a system to prevent information leaks from protected networks. I also worked on a data policy management system called Neon. My latest work at UIUC is on traffic analysis prevention and high-speed intrusion detection. I have a great deal of code that has supported the research described below in my publications. If you are interested in getting a copy, please contact me via email. In the future, I hope to be better about preemptively posting the code for others to use.

I like skiing, theatre, and movies. I also love taking pictures of my new baby daughter, Alina. Check out my pictures site at smugmug.

File Scrub is a security and forensics tool used by the US federal government to review files before they are "downgraded" from a classified system to an unclassified system. File Scrub reviews complex file formats like MS Office and PDF files and removes extraneous meta-data from them before a trusted (byte-by-byte) transfer to external media. I've worked on this project at Los Alamos since 2001 as a researcher and developer. I am currently the principle investigator and development lead for this project.

That's it, check back for more details.
