Grumbach joined the Department of Political Science as an associate professor in 2019 after completing a Postdoctoral Fellowship at the Center for the Study of Democratic Politics at Princeton. His research focuses broadly on the political economy of the United States. He is particularly interested in public policy, American federalism, racial capitalism, campaign finance, and statistical methods. He has also explored the intersections of race and labor in his work and recently co-authored a working paper on “Labor Unions and White Racial Politics.” This study investigated the role of union membership in shaping white racial attitudes and concluded that unions have had a role to play in promoting racist points of view amongst their white members. Since joining the UW Grumbach has taught courses in statistics for the social sciences and in state and local politics. He has also taught on issues of race and inequality in American politics and society.
