Greg is a political theorist and intellectual historian. His research focuses on the history of modern political thought, especially in Britain and France, and on the lessons that can be drawn from that history for contemporary debates in political philosophy.

Recently, his primary interests have concerned the relationship between ideas of democracy, liberalism, and representative government. He has also addressed, among other subjects: toleration and freedom of speech; deliberative democracy and theories of deliberation more broadly; the development of electoral systems and political parties; Enlightenment political philosophy; the history of utilitarianism; the thought of John Stuart Mill and its reception; and modern French political theory.

His book Parliament the Mirror of the Nation: Representation, Deliberation, and Democracy in Victorian Britain was released by Cambridge University Press in 2019 (paperback, 2020). In addition, Greg has published in a number of journals in political theory and the history of political thought. He is currently at work on a book about the constitutional lawyer and political philosopher Albert Venn Dicey.

Greg holds a BA from the University of Chicago and a PhD from Harvard University. He has also been a fellow of Jesus College, University of Cambridge.
