Professor Sommers is an experimental social psychologist interested in issues related to stereotyping, prejudice, and group diversity. His research focuses on two general (and often overlapping) topics: 1) race and social perception, judgment, and interaction; 2) the intersection of psychology and law. In other words, he is interested in how race impacts the way people see and interact with the world in a wide range of social settings. In recognition of this work, in 2008 he received the Saleem Shah Award for Early Career Excellence from the American Psychology-Law Society. For more details regarding publications, ongoing projects, and media coverage of his research, see his lab website.

At Tufts, Professor Sommers teaches courses in Introduction to Psychology (PSY 1), Social Psychology (PSY 13), Experimental Psychology (PSY 32), and upper-level seminars in social psychology and psychology and law. In 2007 he won the Lerman-Neubauer Prize for Outstanding Teaching and Advising at Tufts; in 2009 he was named Gerald R. Gill Professor of the Year by the Student Senate. He has written two general audience books: Situations Matter and This is Your Brain on Sports. He is also a co-author of textbooks for Introductory Psychology and Social Psychology.

Professor Sommers received his B.A. from Williams College and his PhD from the University of Michigan and has been at Tufts since 2003. As demonstrated by his office decor, he has not succumbed to normative social influence while in Boston, as he continues to be an avid Yankees fan. In his free time he hits lead-off for the vaunted Psychology Department softball team, can be found prowling the little league fields of Lexington as a coach of his two daughters' teams, and exerts far more effort than he should digitizing Seinfeld clips and other pop culture examples for his lectures.

The Sommers Lab is always looking for motivated, responsible, and creative students to assist with research projects. Undergraduates in his lab assist with a wide range of duties, including library research, study design, participant recruitment, data collection, data coding/entry, and data analysis. Contact him directly for more information about earning course credit through a research assistant position.
