Brice Didier is postdoctoral researcher at Sciences Po’s Center for International Studies (CERI) and the Institute for Strategic Research (IRSEM). He completed his PhD in political science at the University of Geneva under the co-supervision of Professor René Schwok (University of Geneva) and Professor Christian Lequesne (Sciences Po), on the EU’s foreign policy and the ad hoc initiatives by informal groupings of the ‘big’ member states, in particular the ‘Balkan Contact Group’ initiative on Bosnia and Kosovo, ‘E3’ on the Iran nuclear issue, and ‘Normandy’ on the Russia-Ukraine conflict in Eastern Ukraine. Entitled “European Union Foreign & Security Policy and Big Member States’ Ad Hoc Initiatives: Solving the Effectiveness-Legitimacy Equation”, his dissertation is the laureate of the Global Strategy PhD Prize 2024 awarded by the European Security and Defence College (ESDC) and the Egmont Royal Institute. His postdoctoral research at CERI and IRSEM-Europe focuses on the EU’s strategic adaptation to the US-China rivalry. It follows a series of projects he conducted on transatlantic relations and foreign policy strategies, for which he was notably awarded the Sergio Lopez Perona memorial prize 2017 and the University Association for Contemporary European Studies (UACES)’ Luke Foster Best Article runner-up prize 2022. His research has notably been published in the European Review of International Studies, the Journal of Contemporary European Research, the Routledge Studies in Foreign Policy Analysis, the EU Diplomacy Papers and College of Europe Policy Briefs.
