Dr. Christopher Peterson

Christopher Peterson, Ph.D., is professor of psychology at the University of Michigan, where he has been the director of clinical training and an Arthur F. Thurnau Professor, an award given to honor his contributions to teaching. On two separate occasions, a course he taught has been voted the "best undergraduate class" at the University of Michigan. His research centers on personality and its relationship to adaptation. Peterson is among the youngest researchers included on the Intercollegiate Studies Institute list of the 250 most highly cited psychologists and psychiatrists over the past 20 years.
Dr. Martin E. P. Seligman

Martin E. P. Seligman, Ph.D., is Fox Leadership Professor of Psychology at the University of Pennsylvania. He received both the American Psychological Society's William James Award (for basic science) and the Cattell Award (for the application of science). In 1997, he was elected president of the American Psychological Association by the largest vote in modern history. The National Institute of Mental Health, the National Science Foundation, the Guggenheim Foundation, the Templeton Foundation, and the MacArthur Foundation have supported his research. He is the director of the Positive Psychology Network, and his current mission is to transform social science to work on the best things in life - virtue, positive emotion, and positive institutions - and not just on healing pathology.
