About me

I work on armed conflict, global security and transnational organised crime, as well as peace building, terrorism and governance. I am particularly interested in the role that violent non-state groups play in these dynamics.

I am also Research Associate at the Centre on Conflict, Development and Peacebuilding, Graduate Institute Geneva. I teach at the University of Oxford, supervise students and and advise governments, international organisations and others on topics related to violent non-state actors, organised crime, conflict and peacebuilding.

I serve on a number of boards and committees, including the editorial board of SIRIUS, the Journal for Strategic Analyses, I am member of the International Advisory Committee of the Netherlands Organization for Scientific Research (NWO) in the field of Security and Rule of Law. I serve as an expert for Oxford Analytica, and as Academic Coordinator of the International Network for Conflict and Peace Research on Colombia.
