Ritch C. Savin-Williams is a developmental psychologist, a professor emeritus of Human Development and Psychology. He received the Ph.D. from the University of Chicago, where he studied sex differences in dominance hierarchy formation at summer camp.

Dr. Savin-Williams has written ten books on adolescent development. The last two, Bi: Bisexual, pansexual, fluid, and nonbinary youth (New York University Press, 2021) and Mostly straight: Sexual fluidity among men (Harvard University Press, 2017) follow previous books on the lives of youth with same-sex attractions: Becoming who I am: Young men on being gay (Harvard University Press, 2016); The new gay teenager (Harvard University Press, 2005); and "Mom, Dad. I’m Gay:" How families negotiate coming out (American Psychological Association, 2001). With Kenneth M. Cohen, Dr. Savin-Williams co-edited an undergraduate textbook: The lives of lesbians, gays, and bisexuals: Children to adults (Harcourt Brace, 1996). 

Dr. Savin-Williams is currently writing about the sexual lives of straight males and the resiliency and mental health of sexual-minority youth. His research on differential developmental trajectories attempts to supplant our generic, stage models of identity development with a perspective that explores the similarities of sexual-minority youth with all youth and the ways in which sexual-minority adolescents vary among themselves and from straight youth.

Dr. Savin-Williams is also a licensed clinical psychologist with a private practice specializing in identity, relationship, and family issues among young adults. He has served as an expert witness on same-sex marriage, gay adoption, and Boy Scout court cases. He has served as a consultant for MTV, 20/20, the Oprah Winfrey Show, and CNN and his work has been cited in Newsweek, Time, Rolling Stone, Utne Reader, Fortune, New York Times, Los Angeles Times, Washington Post, USA Today, and Chicago Sun Times. Dr. Savin-Williams received the 2001 Award for Distinguished Scientific Contribution, the 2005 Outstanding Book Award from Division 44 of the American Psychological Association for The new gay teenager, the 2006 APA Science Directorate’s Master Lecture in developmental psychology, the 2009 APA Plenary Address, and fellow status from the Association for Psychological Science. He has also written junior high school curriculum materials for the Unitarian Universalist Association, Beyond pink and blue: Exploring our stereotypes of sexuality and gender.
