Research Overview

The STREETS research agenda is led by Dr. Lara Gerassi whose research focuses on enhancing the health and wellbeing of people who are involved in the sex trade and/or are at risk of sex trafficking.  Her work uses an intersectional, anti-oppressive approach to 1) understand how sex trafficking experiences differ based on race, sex, gender, and sexual orientation among other identities; 2) improve sex trafficking identification practices among health and social service providers; and 3) strengthen the health and community responses for people at risk of sex trafficking and those with lived experiences of sex trafficking and homelessness.  She uses community-engaged approaches to increase methodological rigor of her studies and translate knowledge into practice.

Dr. Lara Gerassi has won the following awards for her impressive commitment to anti-trafficking education and research:

  • Chancellor’s Inclusive Excellence Award (2023) from the UW-Madison
  • Influential Scholar Award (2022) at the International Human Trafficking and Social Justice ConferenceLara Gerassi accepting award.

    (BIRCWH) Scholar (2022-2024) and National Institutes of Health K12 Award
  • Exceptional Mentorship Award (June 2021) from the Undergraduate Research Scholars Program, University of Wisconsin-Madison.

Additionally, STREETS has been able to promote the research of other partners through the UNESCO Chair’s Paper Series and other ad hoc projects. Several research tools have been applied and refined through STREETS and our partners to better identify victims of trafficking and understand the needs of survivors for recovery and wellbeing over the long term. 

Domestic Research Projects

Preparing Practitioners to Identify and Address Sex Trafficking in Northeast Wisconsin. This study assesses social service providers’ knowledge of sex trafficking red flags, screening questions, and engagement practices with young people who are at risk of sex trafficking. The project will result in the development of tailored sex trafficking trainings for regional providers across multiple service sectors (i.e. Child Protective Services, Youth Justice, Social Services).

Healthcare Providers’ Perspectives on Sex Trafficking Risk Assessment. This project is supported by a 4W Innovation Award and explores perspectives on sex trafficking in a large healthcare organization. The purpose of the study is to understand healthcare providers’ strengths and challenges of assessing patients at risk, the relevance and utility of sex trafficking indicators, and the screening and assessment strategies used in clinical practice.

Youths’ Perspectives on Sex Trafficking Assessment Strategies. This study surveys young people with lived experiences of homelessness and/or sex trafficking. The purpose of the study is to understand the relevance to young people of language and strategies that professionals (i.e. social workers, teachers) use to discuss sex trafficking from the perspectives of youth at risk.

The Professional Leadership and Development of Young People with Lived Experiences of Sex Trafficking and Homelessness. This study uses an intersectional, grounded theory approach to understand how young people with lived experiences (ages 16-24) become professional leaders in housing, youth, and ST organizations, and how their professional roles impact their perceived well-being.

“Silence” and “Absence” as Imprints in Women’s Stories of Migration and Human Trafficking

Through the concepts of “silence” and “absence,” this 4W-STREETS plenary at the Women and Gender Studies Consortium 2023 presents a comparative analysis of women’s experiences of trafficking as they travel two migratory routes: from West Africa to southern Europe, and from Central America to the United States. Imposed silence and absence take specific forms in each woman’s journey and story, in each woman’s body, expressing damage, expulsion, exploitation and/or disappearance, but also strength, resilience, and hope. Methodologically, we have developed a patchwork pedagogy that seeks to dialogically connect territories and people to create a choral narrative and a broad social dialogue.

Research Methods & Tools

Research article cover page for Motivational Interviewing.

Motivational Interviewing

Motivational interviewing is an evidence-based practice designed to collaboratively strengthen a person’s commitment to change. Used in a wide variety of practice settings, motivational interviewing is recommended for use with individuals who are at risk of sex trafficking when discussing sex trading or relationships with potential traffickers. This study explored perceptions of motivational interviewing use, applicability, and engagement practices by conducting in-depth, semi-structured interviews with 24-hour service providers in a Midwest region.

Body Mapping Tool

The “Body Mapping for Trafficking Identification Tool” was developed by STREETS affiliate Esperanza Jorge-Barbuzano for use with migrant women in detention centers and other precarious situations where direct questions about trafficking could be dangerous for vulnerable women.  It is based on the Palermo Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children to identify elements of human trafficking in the narratives of women’s lived experiences and health status.  The tool is trauma-informed and has been used successfully to identify trafficking survivors in need of protection who had been overlooked by other authorities.

The 4W Wellbeing Model and Trafficking

The 4W Wellbeing Model, “Gender, Wellbeing, and the Ecological Commons,” recognizes multiple dimensions of wellbeing, which enable people to sense and express more specific and contextualized understandings of their lived experiences. STREETS worked with our colleagues who developed the 4W Wellbeing Model to enlist trafficking survivors in helping us understand what wellbeing means to them. An outcome of this collaboration was a peer-reviewed article in the journal Dignity titled Lifelong Wellbeing for Survivors of Sex Trafficking: Collaborative Perspectives from Survivors, Researchers and Service Providers.

Sexual Violence Research Initiative 

STREETS benefits from other campus partners like the Sexual Violence Research Initiative that includes researchers from the Departments of Gender and Women’s Studies, Psychology, Sociology, Social Work, and the La Follette School of Public Affairs. The participating faculty were chosen across multiple disciplines and engage in research that focuses on (1) psychological aspects of sexual violence; (2) societal aspects of sexual violence; and (3) policy related to sexual violence, at multiple levels (e.g., the university, the state, the nation, or internationally).

Human Trafficking Institute

The Human Trafficking Institute combats trafficking at its source by empowering justice systems to stop traffickers. When justice systems have the tools and training to effectively stop traffickers, they protect the vulnerable and prevent potential victims from being trafficked in the first place.

Their approach implements a proven 3-part model designed to decimate trafficking at its source by stopping traffickers and preventing them from exploiting more victims. Their model helps justice systems more effectively prosecute traffickers and includes specialized teams, targeted trainings, and embedded experts. 

They publish the Federal Human Trafficking Report each year as a tool for justice sector professionals, government agencies, and everyday advocates to understand the U.S. federal response to human trafficking and promote improvements.
