About Me

About Me

I’ve been a practicing clinical, research, and political psychologist for over thirty years. My current work focuses on “psychology for progressive purposes” — applying psychological knowledge to issues of social justice and social change.

I am the former executive director of the Solomon Asch Center for Study of Ethnopolitical Conflict at the University of Pennsylvania, and a past president of Psychologists for Social Responsibility. I’m also a member of the Coalition for an Ethical Psychology, which advocates against complicity in torture and in favor of restoring psychology’s commitment to do-no-harm ethics.

Over my career, I’ve written dozens of scholarly articles published in a variety of leading academic journals. In more recent years, my efforts have turned toward writing for a broader audience. In addition to my popular Psychology Today blog, my writing has appeared in outlets such as the Los Angeles Times, Alternet, and Truthout. In recognition of contributions to the field, I was honored to receive the Anthony J. Marsella Prize for the Psychology of Peace and Social Justice.

I received my undergraduate degree from Princeton University and my doctorate in psychology from the University of North Carolina at Chapel Hill.
