Overview
I am Assistant Professor of Sociology (and Psychology and Neuroscience, by courtesy) 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.
I run the Sociological Study of Cooperation (SSoC) Lab here at Duke.
