Christian Kreuder-Sonnen

Christian Kreuder-Sonnen is a research fellow in the Global Governance department at the WZB Berlin Social Science Center and the scientific coordinator of the DFG Research Group titled “Overlapping Spheres of Authority and Interface Conflicts in the Global Order’ (OSAIC).” His research interests include international institutions and the rise of international political authority. He has published on questions regarding crisis politics of international organizations, contested multilateralism and regime complexity, and institutional change.

At CES, Kreuder-Sonnen will focus on the rise of nationalist populist parties, election victories of authoritarian leaders, and instances of democratic backsliding as characteristics of a wider legitimacy crisis of liberal institutions in OECD countries and beyond. Kreuder-Sonnen will argue that a backlash against international organizations is contributing to the rise of populism.

His book Emergency Powers of International Organizations: Between Normalization and Containment is forthcoming with Oxford University Press. Kreuder-Sonnen’s work has appeared in journals such as the European Journal of International Relations; International Theory; the Journal of Common Market Studies; and Global Constitutionalism.
