Welcome, and thanks for stopping by! I am an Assistant Professor of Sociology at Duke University.

My research is centered on structural and social-psychological solutions to problems of cooperation, collective action, and social order. Much of my work is motivated by my interest in understanding the roles of micro-level attitudes and behaviors in shaping macro-level outcomes. My methodological approach is quantitative and relies largely on experimental data. One key area of my research examines how structured populations promote cooperation in networks. Another examines the dynamics of leadership, power, and influence in groups. And I have focused on understanding additional mechanisms that influence prosocial behavior including moral judgments, status, and religion.

Prior to joining Duke, I enjoyed two fantastic years at the University of Michigan, where I was Assistant Professor of Organizational Studies and Psychology (by courtesy). I received my Ph.D. from the University of South Carolina.
