Adam Slez is a Postdoctoral Research Associate at the Center for the Study of Social Organization in the Department of Sociology at Princeton University. His current research focuses on the spatial organization of mass politics in the United States. This includes studies of the relationship between market proximity and third-party mobilization in the late-19th century, the role of partisanship in the transition to statehood, and the connection between public land policy and the collapse of the American political field in the period between 1789 and 1861. While much of this work is historical, it often involves forays into the world of network analysis, multilevel models, and spatial econometrics.
