Jacob Brown, assistant professor of political science, has been selected as a 2025 Class of Andrew Carnegie Fellow for his work, “The Behavioral Consequences of Partisan Segregation.” Brown is one of 26 fellows from institutions across the United States.
The Andrew Carnegie Fellows Program has supported high-caliber scholarship and research in the social sciences and humanities since 2015. The 2025 Class of Andrew Carnegie Fellows marks the second year of the program’s focus on building a body of research focused on political polarization. Selected from more than 300 nominations, the fellows each receive a stipend of $200,000, making it possible for them to devote their time to significant research and writing.
Brown’s research focuses on where people live, and how where they live influences their politics. His current projects examine the causes and consequences of political segregation in the United States, the influence of where you grow up on future political behavior, and new methods for measuring political geography.
With support from the Carnegie fellowship, Brown will investigate political polarization within populations of voters and how people living in politically like-minded communities affect their views on politics through voter data and geo-tagged Twitter/X interaction data, according to Brown.
Prior to joining BU in 2023, Brown served as a postdoctoral research fellow at the Center for the Study of Democratic Politics at Princeton University. He received his PhD from Harvard University.
“This project builds on my broader research agenda on the causes and consequences of political segregation in the United States,” said Brown. “I am very excited to be selected as a fellow, and grateful to the Carnegie Corporation for supporting my research.”
