My research focuses on three distinct, but related, areas that lie at the intersection of medical sociology, social psychology, and race-ethnicity: (1) racial residential segregation and health, (2) stress-related mechanisms of health inequalities, and (3) social network activation during health-related crises. I draw on theories of race and racism, stress and coping frameworks, and the social network perspective to understand multilevel factors that influence health and health disparities. Methodologically, I employ multiple quantitative methods and draw on U.S. census and individual-level survey data.
