Dr. Stoller is an Associate Professor of Psychiatry and Behavioral Sciences and Director of the Johns Hopkins Broadway Center for Addiction (Johns Hopkins). His area of expertise is treatment and clinical research involving substance use problems and, in particular, the use of methadone and buprenorphine. His research interests have centered on cost issues as they relate to drug abuse and treatment, methods to enhance treatment adherence and retention, and co-occurring psychiatric, medical, pain, and substance use disorders. Published manuscripts and book chapters focus on the use of adaptive stepped care, treatment incentives, and integrated treatment of co-occurring disorders in a single setting. Through his work at Johns Hopkins Health Care, he has developed a related focus on fostering policies and initiatives applied in managed care settings to improve health outcomes and control costs, such as increasing the identification and treatment of substance use disorder and coordinating treatment of general somatic, mental health, and substance use disorders. More recently, since assuming the role of Director of the outpatient addiction treatment program for Johns Hopkins—particularly since his involvement with the American Association for the Treatment of Opioid Dependence, and as the representative on the Board of Directors for Maryland—he has refocused his academic work on the pursuit of increasing access to, and quality of, medication-assisted therapies in Baltimore, Maryland, and nationally. This work has received intense attention over the past two years, especially as it relates to coordinated care using opioid treatment programs as hubs of expertise and coordinating with community physicians prescribing medications for opioid use disorder. Dr. Stoller created and implemented the first known buprenorphine hub and spoke collaborative care model in the nation, and this is the subject of numerous presentations, webinars, and white papers.
