Jack Greenberg is a visiting assistant professor in the department of political science as well as the department of public policy and law. His research focuses on American presidential democracy, investigating how presidential leadership functions in America's separation-of-powers system. His first book, Congressional Expectations of Presidential Self-Restraint, was published by Cambridge University Press in 2025 as part of its Elements in American Politics series. He is currently working on his second book project, "The President's First Moves: The Dynamics of Agenda Construction, 1968-2022," which is a study of presidential domestic policy leadership in the modern era. In the classroom, he is eager to ask students difficult questions about American politics -- and to learn from their answers. He seeks to empower every student as a knowledge creator. Jack is a proud son of Connecticut (having grown up in West Haven) and of the NESCAC, having graduated from Williams College in 2018. He returned to the Nutmeg State for graduate school, earning his PhD from Yale University in 2025.
