Research

My broad research interests include wireless ad hoc networks, game theory, social networks and public policy on privacy. My current focus is on the mitigation of misbehavior in wireless sensor networks using trust and reputation mechanisms. I am also interested in the impacts of security and public policy decisions on privacy issues in these networks.
