Dr. Martin E.P. Seligman is the Director of the Penn Positive Psychology Center and Zellerbach Family Professor of Psychology in the Penn Department of Psychology. He is also Director of the Penn Master of Applied Positive Psychology program (MAPP). He was President of the American Psychological Association in 1998, during which one of his presidential initiatives was the promotion of Positive Psychology as a field of scientific study. He is a leading authority in the fields of Positive Psychology, resilience, learned helplessness, depression, optimism and pessimism. He is also a recognized authority on interventions that prevent depression, and build strengths and well-being. He has written more than 250 scholarly publications and 20 books.
Since 2000 his main mission has been the promotion of the field of Positive Psychology. This discipline includes the study of positive emotion, positive character traits, and positive institutions. As the science behind these becomes more firmly grounded, Dr. Seligman is now turning his attention to training Positive Psychologists, individuals whose practice will make the world a happier place, in a way that parallels clinical psychologists having made the world a less unhappy place.
