From 1986 to today, USIP’s Jennings Randolph Senior Fellowship program has supported research, writing and in-house advising on a wide variety of topics related to peace and violent conflict. The program's more than 320 past fellows have studied everything from the influence of Track Two Diplomacy on U.S.-Russia relations to the effects of oil and other natural resources on prospects for peace.
Current Senior Fellows include:
Louis-Alexandre Berg is an Assistant Professor of Political Science at Georgia State University and a 2020 Jennings Randolph Senior Fellow at the U.S. Institute of Peace. His research examines civil wars and postwar state building, security and justice sector reform, and the effects of foreign aid and military assistance, with a focus on how politics in conflict-affected countries affect the outcomes of international peacebuilding efforts. He also conducts research on the relationship between politics and organized crime in weak states.
Prior to his university appointment, he worked at the World Bank, where he developed new approaches to justice and security programming in conflict-affected countries, and at the U.S. Agency for International Development (USAID) and the U.S. Department of State, where he designed, managed, and evaluated security, justice, and rule of law programs around the world.
He has been a Research Fellow at the Belfer Center for Science and International Affairs at the Harvard Kennedy School, a USIP Peace Scholar Fellow, and a Presidential Management Fellow. He has also served as an expert consultant for the U.S. government, the World Bank, and the United Nations on security and justice programming, and his work has been published in academic and policy outlets, including in the Journal of Conflict Resolution, Journal of Peace Research, International Interactions, Civil Wars, and International Peacekeeping.
Dr. Berg holds a PhD in Government from Georgetown University, a Masters from the Woodrow Wilson School at Princeton University, and a BA from Brown University.
