I am a sociologist at the University of Chicago. I spend most of my time conducting research. In particular, I am interested in how the population composition of contexts (such as levels of diversity or inequality) shapes the emergent network dynamics that underlie social cohesion. I am also interested in using network structure to analyze the intergroup ties that in turn influence behaviors and attitudes. My work spans many kinds of contexts (for example, I have studied classrooms, workplaces, neighborhoods, and quasi-experimental populations). I am usually driven by a theoretically-motivated empirical research question that I then investigate using cutting-edge quantitative methods. My current research projects analyze intergroup dynamics, inequality, and social influence in networks within the areas of immigrant integration, policing, and public health. I also teach courses on applied statistics, academic writing, and social network analysis.
