Mateja Peter, Lecturer


Dr Mateja Peter joined the School of International Relations in September 2015. Previously, she worked as a Senior Research Fellow at the Norwegian Institute of International Affairs (NUPI), where she continues to collaborate on a number of projects.

Dr Peter has also held a transatlantic post-doctoral fellowship (TAPIR) at the United States Institute of Peace, the German Institute for International and Security Affairs, and the Norwegian Institute for Defence Studies. She received her PhD from the University of Cambridge.

Research areas

Dr Peter's interests include:

  • global governance and international organisations
  • peace operations and peacebuilding
  • the politics of international law
  • IR theory (critical and constructivist approaches, international political sociology).

She is interested in both theoretical and policy implications of the shift from short-term to sustained third-party engagements in contemporary interventions. Dr Peter is currently working on a book on international authority in statebuilding and an edited volume on United Nations peace operations in a changing global order.
