Reinier Bergema joined ICCT as a Research Fellow and Project Manager in February 2019. 

He holds a dual Master’s degree in Political Science (International Relations) and Public Administration (Crisis and Security Management), both from Leiden University. His research interests include, inter alia, radicalization, foreign terrorist fighters, and terrorism in Europe.

More specifically, Reinier has conducted research on Dutch jihadist foreign fighters travelling to Syria and Iraq since the violent escalation of the conflict in 2011, combining both quantitative and qualitative research methods. Part of this research involved the setup of a (quantitative) database, consisting of over 220 Dutch jihadists who remain(ed) in Syria and Iraq.

In addition to his work at ICCT, he is an assistant editor at the editorial team of Perspectives on Terrorism and a member of the General Board of the JASON Institute. Prior to joining ICCT, Reinier was a strategic analyst at The Hague Centre for Strategic Studies and a research assistant at Leiden University’s Centre for Terrorism and Counterterrorism.
