Nancy L. Segal

Nancy L. Segal is an American psychologist and one of the world's foremost experts on twins. She is a professor at California State University, Fullerton, where she directs the Twin Studies Center, and has published extensively on the science of twinship. Deliberately Divided examines cases where twins were separated — sometimes deliberately — and the extraordinary insights their stories provide into the relative influences of nature and nurture on human development. Segal's research combines rigorous science with compelling human stories. The audiobook and book versions offer listeners and readers a fascinating exploration of one of psychology's most important questions. Segal's work appeals to anyone interested in psychology, genetics, identity, and the remarkable stories of twins reunited after years apart.
