John Bancroft, MD, previously Director (May 1, 1995 – April 30th 2004) of The Kinsey Institute, has been involved in various aspects of sex research for the past forty years. He was Clinical Reader in Psychiatry at Oxford University from 1969-1976; then leader of the Behaviour Research Group at the Medical Research Council's Reproductive Biology Unit in Edinburgh until 1995.

His research has mainly focused on (i) the relationship between reproductive hormones and sexual behavior, including the impact of the menstrual cycle and fertility control on sexual behavior and wellbeing of women; (ii) psychophysiological aspects of male sexual response; (iii) sexual dysfunction in men and women.

Dr. Bancroft's clinical experience in the management of sexual problems spans more than 35 years. For much of that time, he has trained many other health professionals in sex therapy. He is the author of Human Sexuality and Its Problems 3rd Ed, (2009). 

Prof. Dr. Janssen's research interests include the psychophysiology of sexual desire and arousal, the effects of emotions on sexual response and behavior, and relationships, sexuality, and health. With his research he aims to improve our understanding of the factors and processes that influence sexual and relationship satisfaction and of the determinants of risky sexual decision-making, sexual dysfunction, sexual compulsivity, and sexual aggression.

A large part of Prof. Dr. Janssen's work focuses on the award-winning Dual Control Model of Sexual Response, which he introduced with John Bancroft, M.D. and which, with its focus on individual differences in the propensity for sexual excitation and inhibition, opened up a new research agenda with wide relevance. The model is being used and tested by researchers around the world in studies on sexual health topics as varied as sexual risk taking, sexual dysfunction, sexual compulsivity, and sexual aggression. Studies in over 45,000 men and women have consistently shown that large individual differences exist in sexual excitation and inhibition proneness, and suggest that this variability is associated with, on the one end, a vulnerability to sexual dysfunction and, on the other end, an increased likelihood of engaging in risky sexual risk behaviors (including sexual infidelity) and sexual aggression.

Prof. Dr. Janssen also studies the relationship between sexual and nonsexual emotions (e.g., happiness, sadness, anger) and how these, separately and in interaction, influence sexual functioning, behavior, and satisfaction, in individuals as well as in couples. In approaching this work, Dr Janssen applies questionnaire, experimental, observational, psychophysiological (including fMRI), daily diary, as well as interview and focus group methods.

Leonore Tiefer, PhD, author, educator, researcher, therapist and activist has specialized in many areas of sexuality. She began with a Psychology PhD on hormones and hamsters (University of California, 1969) and an academic position and animal laboratory (Colorado State University, 1969-1977). Responding to the call of feminist politics and the world of sexology for people, she later re-specialized in clinical psychology (New York University, 1988) with a focus on sex and gender problems. Beginning in 1977 her New York City career took her to Downstate Medical Center, Beth Israel Medical Center and then to Montefiore Medical Center where she was employed in the Urology Department and co-directed the Sex and Gender Clinic from 1988-1996. She is currently Associate Clinical Professor of Psychiatry at the New York University School of Medicine and has a limited private psychotherapy and sex therapy practice in Manhattan.

Dr. Tiefer has written widely about the medicalization of men's and women's sexuality. The website of her educational anti-medicalization campaign, newviewcampaign.org, is a major resource on this topic for journalists, colleagues, and the public. Dr. Tiefer has received many professional awards, e.g., 1994 Alfred C. Kinsey Award and 2004 Distinguished Lifetime Scientific Achievement Award from the Society for the Scientific Study of Sexuality and 2004 Lifetime Career Award from the Association for Women in Psychology. She has been elected to many professional offices within sexological and feminist organizations (e.g., 1986 National Coordinator of Association for Women in Psychology, 1993 President of the International Academy of Sex Research). She served as Vice-Chair of the Board of Directors of the National Coalition against Censorship (ncac.org) and on many committees at her New York City Unitarian Universalist Church.

Her Westview Press book, Sex is Not a Natural Act and other essaysnow in a 2nd edition (2004), has been translated into several languages. In 2001 she co-edited an important feminist sexology collection, A New View of Women's Sexual Problems, that grew out of the New View educational campaign (newviewcampaign.org). She also co-authored a classroom and workshop teaching manual (2003) to accompany this text. The New View campaign has held 4 scholar-activist conferences, testified before the FDA, provided fact sheets and briefings for media, and generated articles and chapters that are influencing the way students and professionals are taught about human sexuality.

In 2013, Dr. Tiefer moved from focusing exclusively on the medicalization of sex to a larger perspective on overtreatment and over-diagnosis as co-organizer of the successful conference, Selling Sickness: People Before Profits.
