My work focuses on a better understanding of high-stakes, real-world conflicts and how they might be resolved peacefully. Since 1996, I work with Dutch, other European and North American police forces, justice departments and the military on topics related to how to promote behavioral change, on intelligence gathering and deception detection, and on the psychology of victimization and conduct after capture. I am also interested in issues related to moral (dis)engagement, third-party conflict interventions and cultural differences in police-civilian interactions. In 2012, I received the Rubin Theory-to-practice-reward, co-sponsored by the International Association of Conflict Management (IACM) and the Harvard Program on Negotiation.
