Dr. Orion Mowbray examines two areas of research: (1) Promoting access to mental health services, and (2) Understanding differential outcomes associated with mental health services utilization. In these specific areas of research, Dr. Mowbray has examined the experiences of multiple vulnerable populations, including how persons in the criminal justice access mental health and substance use services, how public mental health systems adopt medication-assisted treatments for persons with substance use disorders, caregiver needs and child behavioral health problems among those in the child welfare system, and how persons with chronic health problems experience mental health and substance use related problems.
