- Community work and activism
Williamson has organized an annual International Human Trafficking, Prostitution and Sex Work Conference at the University of Toledo since 2004. She also chairs the Lucas County Human Trafficking Coalition, which includes local criminal justice, social service, and health care agencies, along with businesses, university members, churches, citizens, and adult survivors, and the FBI Innocence Lost Task Force. In 1993, Williamson founded Second Chance, an organization that develops individualized service plans for women and children survivors and victims in Toledo, Ohio.
Williamson has also been active in advocating for legislation surrounding sex trafficking on a state level. She supported Ohio Senate Bill 235, which implemented stricter penalties for sex traffickers and better protection for trafficked and exploited victims. She is a vocal advocate of the currently proposed Ohio Senate Bill 262 – or “Safe Harbor” legislation – which would prevent Ohio from treating victims of child sex trafficking as criminals.
The majority of Williamson’s research is conducted in the Toledo and surrounding Ohio community. Her research has focused on examining victims’ experiences, as well as to better understand how children and women are forced or coerced into the sex trade and the role of the trafficker.
In February 2010, Williamson, in conjunction with the Trafficking in Persons Study Commission, published research about the prominence of the child sex trade in Ohio under then Ohio Attorney General Richard Cordray. According to the results, 1,000 American-born children are forced into the sex trade in Ohio every year and about 800 immigrants are sexually exploited and pushed into sweatshop-type jobs. The report cited Ohio’s weak laws on human trafficking, its growing demand for cheap labor, and its proximity to the Canadian border as key contributors to the illegal activity.
Her 2010 study, entitled “Exiting Prostitution: An Integrated Model,” focused specifically on the challenges encountered by women attempting to exit the commercial sex industry. Her 2009 study, “Domestic Minor Sex Trafficking: A Network of Underground Players in the Midwest” explored women’s experiences with: (a) violence, (b) HIV risks and condom use, (c) emotional and physical health, (d) substance use, (e) home life and street life, and (f) experiences with local 130 systems including the juvenile justice system, the social service system, and the health care system. A 2002 study by Williamson entitled “Pimp-Controlled Prostitution” focused on understanding the traditional pimp-prostitute relationship through qualitative research.
Awards and recognitions 
In 2009, Williamson was inducted into the Ohio Women’s Hall of Fame for her work on sex trafficking and prostitution issues throughout Ohio. In 2009, Second Chance, founded by Williamson, received the FBI Director’s Community Leadership Award for its efforts.
