Psychology Professor and Associate Vice Provost at Lehigh University. I study how social identities – people’s conceptions of themselves grounded in the groups they belong to – influence conformity and dissent, intergroup relations, solidarity and social change, public health, and leadership. Currently, we are particularly interested in relationships between institutions and identities, and their implications for issues ranging from discrimination to privacy to behaving badly online.
In 2021, I published my first book with longtime collaborator (and grad school officemate), Jay Van Bavel. The Power of Us received a starred review from Publishers Weekly, and a warm review in Science. We were awarded the William James Award from the American Psychological Association for the best book of 2021.
