Elizabeth LetourneauElizabeth J. Letourneau, PhD is an associate professor and director at the Moore Center for the Prevention of Child Sexual Abuse, Department of Mental Health, Bloomberg School of Public Health, Johns Hopkins University. For more than 25 years she has conducted research involving the evaluation of clinical practice and legal policy related to adult and adolescent sexual offending. Specifically, she has developed and/or evaluated assessment tools for juvenile and adult sexual interest in children and sexual recidivism risk. She has also contributed substantively to the literature on treatment of sexual offenders, including leading the largest randomized controlled trial evaluating an intervention for youth who have sexually offended. She has served as primary investigator on six studies evaluating adult and adolescent sex crime policies, findings of which have been presented internationally (e.g., to INTERPOL), nationally to US Department of Justice Agencies (e.g., US Immigration and Customs Enforcement), cited in federal and state court cases including three state supreme court cases, and provided as testimony to state and federal policy makers.  As the inaugural director of a research and policy center focused on the prevention of sexual abuse, she more recently turned her focus to the primary prevention of child sexual abuse.  She has served as president for the Association for the Treatment of Sexual Abuse, the largest international member organization that focuses on the prevention of sexual abuse and sound policy and practice with people who have offended or at risk to do so.
