His related work connects these institutional dynamics to substantive domains including policing, redistricting, and voting rights. His work has been published in the Journal of Race, Ethnicity, and Politics and the Journal of Experimental Political Science.
His scholarship combines computational social science with causal inference to study elite political behavior and institutional dynamics. He specializes in machine learning and natural language processing for political text and administrative data, alongside statistical methods for descriptive, predictive, and causal analysis.
