Benjamin J. Morasco is a Professor of Psychiatry in the School of Medicine at Oregon Health & Science University. His research focuses on chronic pain, opioid use disorder, and addiction medicine, with particular emphasis on substance use disorders, pain management, and the intersection of psychiatric conditions. His latest work investigates the impact of regulatory reform on VA opioid treatment programs, the association between cannabis use and insomnia in veterans with chronic pain, and mental health care utilization following suicide attempts. He has published pivotal findings on buprenorphine for patients on high-dose long-term opioids in JAMA Internal Medicine and leads trials on light therapy for sleep in veterans with traumatic brain injury. His research also explores mindfulness in co-occurring PTSD and substance use disorders, alongside implementation science in shared decision-making for rheumatoid arthritis.
