Peter Gray has conducted and published research in neuroendocrinology, developmental psychology, anthropology, and education. He is author of an internationally acclaimed introductory psychology textbook (Psychology, Worth Publishers, now in its 8th edition, with David Bjorklund as co-author), which views all of psychology from an evolutionary perspective. His recent research focuses on the role of play in human evolution and how children educate themselves, through play and exploration, when they are free to do so. He has expanded on these ideas in his book, "Free to Learn: Why Unleashing the Instinct to Play Will Make Our Children Happier, More Self-Reliant, and Better Students for Life" (Basic Books, 2013). He also authors a regular blog, called "Freedom to Learn," for Psychology Today magazine. He is a founding member of the Alliance for Self-Directed Education and of the nonprofit Let Grow.
Peter Gray grew up primarily in various small towns in Minnesota and Wisconsin, but his family moved to Vermont when he was 16, and he has been east ever since. He studied psychology and biology at Columbia College in New York City and then earned a doctorate in biological sciences at the Rockefeller University. Ever since then, the location of his work has been in the psychology department at Boston College, where he served for 30 years as a professor and now, though retired from teaching and administrative duties, retains the title of Research Professor.
