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. Among numerous awards, in 2010 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.
