Sarah’s research is broadly concerned with the mechanisms driving social differentiation and inequalities in resources, opportunities, and power across social groups and places. A first stream of research examines housing and property ownership as a driver of group and place differentiation. Sarah’s historical/ethnographic projects in this area focus on property rights in Mexico City and special assessment districts in Milwaukee. A second stream examines Mexico-U.S. migration in the early 20th century, including explorations of how Mexico’s agrarian reform shaped the outflow of migrants and how skin color stratified migrants’ economic attainment after settlement in the U.S. A third stream of research asks how new information technologies are reshaping power relations both within U.S. households and between landlords, property managers, and tenants. Sarah employs a variety of methods in her research, including historical methods, interviews & ethnographic methods, and quantitative spatial analysis. Sarah is currently a Postdoctoral Research Fellow for Project SPLICE at the School of Public Health.
