Despite the gravity and prevalence of human trafficking, there is a notable lack of evidence on what programs work to reduce trafficking and support victims. To support research on this critical and understudied topic, IPA has established the Human Trafficking Research Initiative in partnership with the Program to End Modern Slavery (PEMS) at the U.S. Department of State, with the guidance and support of co-scientific advisors Guy Grossman (University of Pennsylvania) and Cecilia Hyunjung Mo (University of California, Berkeley).
