Justin Greenman
Bio
“Justin is a third-year PhD student specializing in American Politics and Qualitative & Archival Methods. His research broadly focuses on the influence of political parties and governing coalitions on the development of separation of powers dynamics between Congress and the President, and the never-ending battle between the two for institutional supremacy. He has various working papers exploring different eras between the two branches, and the individuals and ideas that shaped those conflicts. Previous research includes a “A No Man’s Land Somewhere Between the Legislative and Executive Branch,” a Presidential Studies Quarterly recontextualization of the modern vice presidency and its role within the executive branch.
At Yale, he serves as one of the department’s elected graduate student representatives, as well as coordinator of the Dahl Research Scholars Program through ISPS. Justin graduated summa cum laude from the University of Pennsylvania and with a master’s in history from New York University. In his free time, you can find Justin watching classic TV shows or yelling during a Jets or Mets game.”
