Emile Bruneau

Emile Bruneau, 47, a neuroscientist who researched human conflict at the University of Pennsylvania’s Annenberg School for Communication, died Sept. 30 of brain cancer at his Philadelphia home.

Dr. Bruneau studied how hatred or dehumanization of people from other groups can lead to violence.

His work took him to Colombia, where he examined how former rebel guerrilla fighters with FARC reintegrated into society after years of war; to the conflicts in the West Bank and Israel, and to Hungary, where non-Roma teachers dehumanized Roma children in class.
