Biography
The general goal of my research is to better understand the structure and dynamics of social interaction. To that end I am interested in a number of related topics, including the structure and evolution of social networks, the origins and consequences of social influence, and the nature of distributed "social" search. My approach to research is problem-driven and interdisciplinary, drawing on insights and methods from sociology, psychology, and economics, as well as from physics and computer science. I am also interested in exploring the potential of electronic communications data, such as email, as well as online communities and web-based experiments, to resolve some of the measurement difficulties associated with studying human interactions and social dynamics.
