Ashli J. Sheidow, Ph.D., is a Senior Research Scientist at the Oregon Social Learning Center (OSLC). She recently was Professor in the Department of Psychiatry and Behavioral Sciences (Family Services Research Center) and the Department of Pediatrics, Medical University of South Carolina. She received her Ph.D. in 2001 in clinical psychology from the University of Illinois at Chicago, conducting research at the Institute for Juvenile Research and receiving clinical training in Cook County Hospital’s adolescent division. Dr. Sheidow’s research interests have focused broadly on the development, prevention, and treatment of adolescent and young adult psychopathology and delinquency from an ecological perspective, with concentrations in co-occurring disorders, effective dissemination of evidence-based practices, and advanced quantitative methods. Her work, funded primarily by NIDA and NIMH, has included intervention development and evaluation projects, as well as dissemination and implementation research. She has been NIDA-funded since 2003 for her work developing and evaluating an ecological clinic-based treatment for youth diagnosed with comorbid substance use and mental health disorders, and she has led development of a Multisystemic Therapy adaptation for justice-involved emerging adults with serious mental health conditions. In addition, Dr. Sheidow has collaborated on a variety of other treatment development, quantitative, and economic evaluation projects for federally-funded studies of evidence-based practices, as well as projects on training therapists in youth substance abuse interventions. She is on the editorial boards of the Journal of Child and Adolescent Substance Abuse and the Journal of Behavioral Health Services Research, and she has led programming for national conferences on adolescent substance abuse research.
