John Brake

John Brake researches the social dynamics of global governance regimes and states’ costly compliance with international rules across a wide array of issue areas, from military intervention to nuclear proliferation to climate change mitigation. His graduate work has drawn upon the social theory of Pierre Bourdieu and Erving Goffman to explore “performative restraint” in international politics. This project provides a novel theoretical framework for how the expression of national exceptionalism, typically associated with bellicose and disruptive foreign policies, can also lead to rule-following and prosociality. John is now extending these ideas into the domains of international human rights law and the laws of war. His other research interests include, broadly, the historical sociology of Chinese law and politics, and normative questions in US-China relations.

John is currently completing his PhD in Politics and International Studies at the University of Cambridge, where he is a Marshall Scholar and has also served as Editor-in-Chief of the Cambridge Review of International Affairs. He holds an MMS in Global Affairs from Tsinghua University in Beijing, where he was a Schwarzman Scholar, and a BA in Politics with highest distinction from the University of Virginia, where he was a Jefferson Scholar. John will pursue his JD in the University of Chicago Law School’s Class of 2025.
