Lacombe is an Assistant Professor of Political Science at Barnard College, Columbia University. His research focuses on understanding and explaining political power in the United States. It engages with interest groups and political parties, social identity and political ideology, inequality and representation, and American political development. He uses the case of the National Rifle Association to identify and explain how interest groups can develop and use group-specific social identities and ideologies to advance their political agendas. He also studies the political preferences and behavior of U.S. billionaires, and the diverse ways they seek to influence politics.
