Research Interests 

My main research interests are in Social Network Analysis, Social Computing and Information Economics. I am especially interested in research involving the development of technological applications and computational methods for modeling and understanding human behavior in social networks.    My other research interests include: Location Aware Systems; Technology Acceptance; Decision Support Systems; and Information Security.
