Research

My research interests are in optimal resource allocation, sequential decision theory, incentive design, and performance modeling and analysis, all within the context of communication networks. My most recent research activities involve online learning, modeling and mining of large scale Internet measurement data concerning cybersecurity, and the design of incentive mechanisms aimed at encouraging the adoption of better security practices. Here are some recent publications in these areas.
