David Traven joined CISAC as a MacArthur Nuclear Security Fellow in July 2014. He received his PhD. in Political Science at Ohio State University in 2013. From January 2013 to June 2014 he was a Visiting Assistant Professor of Political Science at Kenyon College. His research examines the evolution of the law and ethics of war in international relations, and he is particularly interested in understanding how moral cognition and emotion shape the creation of norms that protect the victims of armed conflict, especially civilians. Dr. Traven is currently working on a book manuscript that examines how moral intuitions influence the creation and the effectiveness of the norms of war across cultures.
