Brian Collisson, PhD, is a social psychologist. He and his team of graduate and undergraduate students conduct research at the interface of social perception (people’s impressions of others), prejudice, and close relationships. His team’s work has been published in scholarly journals—Psychological Science, Journal of Social and Personal Relationships, and Social Psychological & Personality Science—and has garnered popular media attention. Projects in his lab typically focus on relationship processes, prejudicial attitudes toward romantic couples (e.g., interracial, age-gap, mixed-weight couples), and perceptions of dating “outside of one’s league.” He is accepting undergraduate and graduate students to work with him; email for more information.
