Jonas Claes is a senior program officer at the U.S. Institute of Peace, where he conducts research and analysis on the prevention of electoral violence and mass atrocities. In this capacity, Claes coordinates prevention projects and consults senior U.S., U.N. and EU officials in fine-tuning prevention practices. He has engaged in election observation, research and training around the world, including in Kenya, Liberia, Bangladesh, Suriname and Honduras.

Mr. Claes is the editor of “Electing Peace,” a USIP research volume that takes an important step at identifying what works, and what does not, in preventing election violence. The book evaluates the utility of preventive diplomacy, security sector engagement, peace messaging and several other instruments for the purpose of election violence prevention. Claes has written extensively on the responsibility to protect as well, including a journal article on “Protecting Civilians from Mass Atrocities: Meeting the Challenges of R2P Opposition” published in Global Responsibility to Protect, and a chapter on “The Responsibility to Prevent” in the Cambridge volume The Role of Business in the Responsibility to Protect.

Previously, Jonas served as senior program specialist in the Center for Conflict Management, supporting USIP’s work on conflict analysis and prevention, including the Working Group on the Responsibility to Protect co-chaired by former Secretary of State Madeleine Albright and the late Ambassador Richard Williamson. In 2016, he worked from the European Institute of Peace (EIP) office to continue his work on election security from Brussels, and to integrate the work of USIP and EIP. He holds a master’s degree in security studies from Georgetown University’s School of Foreign Service, and a master’s degree in international relations from the Katholieke Universiteit Leuven (Belgium).
