about me


I am an Assistant Professor of Sociology at Columbia University. I received my PhD in Sociology and Social Policy from Princeton University, and I completed a postdoc in the Population Studies and Training Center at Brown University.

Broadly, I am interested in intergroup relations and boundary processes, especially as they pertain to race, ethnicity and nationalism. Most of my research explores the impact of demographic diversification––real and perceived––on intergroup relations in the United States. I draw on a range of quantitative methods and data sources, including original lab, survey, and field experiments.

Ongoing projects examine the relationship between racial/ethnic diversity and cooperation, boundary-drawing in the wake of diversification, the sources of skin color stratification, the nature of the criminal-immigrant stereotype, and the public expression of sensitive attitudes on topics like race.
