Mary Koss, PhD, is a Regents’ Professor in the Mel and Enid Zuckerman College of Public Health at the University of Arizona. She is co-editor a two book series for the American Psychological Association, Violence Against Women and Children (2011). She published the first national study on acquaintance rape in 1987 and developed the most frequently used survey to measure unwanted sexual experiences. She consults nationally and internationally on sexual assault. She was the principal investigator of the RESTORE Program; the first restorative justice program for sex crimes among adults that was quantitatively evaluated. Her current projects include developing risk assessment and therapeutic approaches for those found responsible for campus sexual misconduct and a primary prevention program focusing on alcohol serving establishments. She is a member of the working group to develop a Best Practices manual for the assessment of campus climate and a second group to develop and advocate for innovation in collegiate response to sexual misconduct within OCR and VAWA guidelines. She has been selected by the American Public Health Association and the US Departments of Justice and Education to serve on the CDC Think Tank to create a comprehensive approach to sexual violence prevention as part of Not Alone: The First Report of the White House Task Force to Protect Students from Sexual Assault. She was the 8th recipient of the Visionary Award from End Violence Against Women International, the law enforcement training and technical assistance organization. In 2013 the Mary P. Koss Profile in Courage Award was created by the One in Four USA Organization to honor her career contributions to using science to heighten awareness of rape.
