My training is the biological sciences, but with broad interests in human nature, including its evolution. My writings, including academic and trade books, as well as over 200 scientific papers, cover the disciplines of animal behavior, evolutionary biology, neurobiology, cognitive neuroscience, biological anthropology, evolutionary psychology, linguistics, economics, cognitive development, and philosophy. From 1992-2010 I was a professor at Harvard University. From 2010 and ongoing, I am working with at-risk youths, harnessing the discoveries of the mind and brain sciences to both bring new tools to this important are of education and human welfare, and to help ameliorate the lives of these children. I continue to work on scientific papers, teach, and write for the general public.
