I'm currently working on a framework for sharing network security data
between multiple organizations for faster and more comprehensive
incident response, with a goal of automation and future incident
forecasting. This is a collaborative effort with USC/ISI,
Los Alamos National Laboratory, and Colorado State U.
Other current work entails developing and evaluating content reuse
detection techniques on web-scale datasets, evaluating availability
of cloud services and systems, and securing personal cloud applications.
Interests include network protocols and analysis, data
visualization, information security and privacy, social
Previously, I worked on delay-tolerant networks; I continue to
keep as up-to-date as I can (and maybe write some code).
