Professor Caplan’s principal research interests are in international organisations and conflict management, particularly post-conflict peace- and state-building. He is currently researching how the principal peacebuilding actors within the United Nations system differ in their understandings of the characteristics of and requirements for a consolidated peace, and the implications that these differences have for the formulation and implementation of coherent peacebuilding strategies. The project focuses on the technical, organisational and political challenges of devising operational measures of effectiveness, in particular measures of progress towards the achievement of a consolidated peace.
Professor Caplan has served as a Specialist-Advisor to the Select Committee on Foreign Affairs in the UK House of Commons; a Research Associate at the International Institute for Strategic Studies (IISS); and New York Director of the Institute for War and Peace Reporting (IWPR). He has also served as a consultant to the UN Peacebuilding Support Office (PBSO) and to various national governments. He has also been a member of the World Economic Forum's Global Agenda Council on Fragile States.
