Adar Eisenbruch

Assistant Professor of Psychology


Dr. Eisenbruch received his PhD from the University of California, Santa Barbara, and completed a post-doctoral fellowship at Harvard University. Prior to joining Marist, he was an Associate Researcher at Future Laboratories, a Visiting Assistant Professor at SUNY Purchase, and an Assistant Professor at Mount Saint Mary College. Dr. Eisenbruch’s research takes an evolutionary approach to the problems of human social life. In particular, he studies the relationships between hormones and behavior, and the ways that our contemporary social preferences (e.g. who people want to be friends with) have been shaped by the problems faced by our ancestors.
