Mona Sue Weissmark is a clinical and social psychologist whose work on diversity and the psychological roots of injustice has received global recognition. She is the author of the books Doing Psychotherapy Effectively (University of Chicago Press), and Justice Matters: Legacies of the Holocaust & World War II (Oxford University Press). The founder and former director of the Program Initiative for Global Mental Health Studies at the Buffett Institute for Global Studies at Northwestern University and the founder and former director for The Center for Social Justice in Chicago, Dr. Weissmark is also part-time Associate Professor of Psychiatry and Behavioral Sciences at Northwestern University's Feinberg School of Medicine. Currently, she teaches the course 'Psychology of Diversity' and conducts research on the science of diversity and justice at Harvard University.

"In this ambitious, potentially timely project, Weissmark embraces scientific theorizing and empirical evidence to examine diversity on personal, interpersonal, and national levels. She invites readers on a journey that begins with a historical overview of diversity, moves through child development and the cognitive processes of categorization and judgment making, turns to diversity in relationships and groups, and finally looks at social justice and ethnic conflicts." -- I.
