I have been a faculty member at the University of Maryland School of Medicine since completing my fellowship in Addiction Medicine in 2015.  Now full-time, I divide my clinical responsibilities between the Division of Addiction Research and Treatment (DART) in the Department of Psychiatry and the Department of Family and Community Medicine. As medical director of the UMMC Addiction Treatment Programs at 1001 West Pratt Street, , I treat patients, coordinate clinical care, host research projects, and participate in the clinical education of medical students, psychiatry residents, and addiction fellows. We are working to further the integration of medical and mental health services in the substance use disorder treatment setting. In addition, as the associate director of the Addiction Medicine Fellowship, I collaborate in fellow recruiting, program accreditation, and educational seminars.

In the Department of Family and Community Medicine, I precept medical students and residents in their training. In addition, I am undertaking writing and curriculum development, especially in domains that relate to the intersection of primary care, care of chronic illness in patients with addiction, and enhanced treatment of substance use disorders.
