Richard Caplan is Professor of International Relations and an Official Fellow of Linacre College. His principal research interests are concerned with international organisations and conflict management, with a particular focus on peacekeeping and 'post-conflict' peace- and state-building. He is the author and editor of several books, among them Europe's New Nationalism: States and Minorities in Conflict (Oxford University Press, 1996); A New Trusteeship? The International Administration of War-torn Territories (IISS/Routledge, 2002); Europe and the Recognition of New States in Yugoslavia (Cambridge University Press, 2005); International Governance of War-torn Territories: Rule and Reconstruction (Oxford University Press, 2005); and Exit Strategies and State Building (Oxford University Press, 2012). His most recent book is Measuring Peace: Principles, Practices and Politics (Oxford University Press, 2019).

Professor Caplan is Principal Investigator of the ESRC-funded project 'After Exit: Assessing the Consequences of United Nations Peacekeeping Withdrawal', which is investigating conditions on the ground in countries that have played host to large-scale UN peacekeeping operations in the five-year period following the closure of these operations. See the After Exit website for more details. He is also a Principal Investigator and lead researcher of the Oxford Martin School-funded programme on 'Transboundary Resource Management', which is exploring the scope for cross-border co-operation on natural resource management in the eastern Nile River Basin and the Jordan River Basin, where growing pressures on water and energy threaten regional destabilisation. See the Oxford Martin School website for more details.

Professor Caplan has held fellowships and received grants from the British Academy, the British Council, the Carnegie Corporation of New York, the Economic and Social Research Council (ESRC), the Folke Bernadotte Academy, the John Fell OUP Research Fund, the Leverhulme Trust, the MacArthur Foundation, the Oxford Martin School, and the US Institute of Peace. He has held visiting positions at the European University Institute (EUI), University of Konstanz, University of Pavia, Princeton University, and Sciences Po (Paris).
