Social Networks

Social relationships can significantly influence people's emotion, cognition and behavior within and between groups, organizations, communities and societies. Using a variety of social network theories, and data collection and analysis methods, we are interested in studying how properties of social ties influence technology use, group decision making, collaboration, knowledge management, risk communication, health communication and so on. Current projects include a study of social networks on mobile phones to provide peer support, research into mobile and online social networking services, a study of social ties in Wikipedia, USDA funded research on social networks and risk communication, work on leveraging social network sites to reduce energy use, studies in the influence of communication networks on organizational elements such as team performance and team leadership, and NSF funded research on the impact of social ties on knowledge management in cross-culture teams.
