Principal Investigator

Adam Pearson, Ph.D., (CV) is an associate professor of psychology at Pomona College and member of the graduate faculty in the Division of Behavioral and Organizational Sciences at Claremont Graduate University.  He received his PhD in Psychology from Yale University. His research explores how people navigate diversity, with a particular interest in understanding how group memberships influence how people perceive and respond to societal problems like climate change and inequality. He teaches social psychology, research methods, introductory psychology, and a seminar on contemporary prejudice. When not pondering the roots of intergroup conflict, he can be found enjoying craft beers and hiking in SoCal with his shepherd mix.
