Alin Coman

Alin is an Associate Professor of Psychology and Public Affairs, with a joint appointment between the Psychology Department and the School of Public and International Affairs. A native of Romania, Alin obtained his B.A. from Babes-Bolyai University, where he majored in Experimental Psychology. Defying the odds, and being completely uninformed about the grad school application process in the United States, he applied to only one department, the New School for Social Research (The New School), from which he graduated in 2010 with a Ph.D. in Social, Cognitive, & Developmental Psychology. It’s where he learned to overcome disciplinary boundaries in answering research questions. After a brief stint as a postdoc at the University of Pittsburgh and Carnegie-Mellon University’s Robotics Institute, he joined the Psychology Department at Princeton University, where he currently directs the Cognition in Collectives Lab. Here, he advocates for a similarly interdisciplinary approach to answering research questions with his students and collaborators.
