Stacy Calhoun, Ph.D., is a researcher at the UCLA Integrated Substance Abuse Programs and the Greater Southern California Node of the National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) with over 19 years of experience in behavioral health and criminal justice research. Her work is largely centered around integrated systems of care, especially in school and criminal justice settings. She recently led an evaluation of an integrated physical and behavioral health screening program for high school students and a qualitative study with school stakeholders across California to identify barriers and facilitators to implementing integrated models of care in K-12 schools to address trauma, substance use, mental health, physical health problems, and other issues such as gang involvement and delinquency in general. Building on this work, she received funding from the National Institute of Justice (NIJ) to conduct a randomized controlled trial of a gang prevention program that has been incorporated into a school-based clinic that provides integrated services for students. She is also the principal investigator of several state- and county-funded projects evaluating rehabilitative programming, services, and practices in criminal justice settings. As part of her efforts to disseminate research findings to a larger audience, she serves as the literature editor for the Sex Offender Law Report and the Juvenile Justice Update to highlight current findings from the literature for a practitioner audience.
