Jordan P. Davis

Jordan P. Davis, Ph.D., is Professor at the Brown School at Washington University in St. Louis. He comes to WashU from the RAND Corporation, where he served as Senior Policy Researcher, and previously held a faculty appointment at the University of Southern California’s Suzanne Dworak-Peck School of Social Work. He received his Ph.D. in Social Work from the University of Illinois at Urbana-Champaign in 2017.

Dr. Davis leads a nationally recognized, extramurally funded research program at the intersection of trauma and substance use disorders. His work focuses on the etiology and treatment of PTSD, alcohol and other substance use disorders, and co-occurring psychiatric conditions, with particular emphasis on individuals historically underserved by existing systems of care. He integrates ecological momentary assessment, wearable biometric sensing, machine learning, and advanced longitudinal modeling to understand how trauma and stress shape behavioral health, and to identify when and how to intervene most effectively.

His intervention science includes randomized controlled trials of mobile health tools targeting co-occurring PTSD and substance use, and his policy-facing work at RAND has reached federal lawmakers and veteran-serving organizations nationwide. Dr. Davis has received extramural funding from the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Alcoholism, and several private foundations, and holds editorial roles at several leading journals, including Deputy Editor of Stress and Health and Associate Editor of Addictive Behaviors. He has served as Chair of APA Division 50’s Collaborative Perspectives on Addiction conference for four years and will direct a NIDA-funded T32 training program at WashU.
