Dr. Strain is the Director of the Johns Hopkins University Department of Psychiatry and Behavioral Sciences Behavioral Pharmacology Research Unit (the "BPRU"). The BPRU is one of the nation's oldest research programs dedicated to studying substance use disorders, and conducts rigorous research to further our understanding and treatment of these conditions. The BPRU has 15 full-time faculty, and conducts clinical research with all types of drug abuse. He is also the Director of the Johns Hopkins Center for Substance Abuse Treatment and Research, and the Executive Vice-Chair for Psychiatry at Johns Hopkins Bayview Medical Center. He maintains an active research program in substance abuse related issues, provides clinical care to patients, teaches medical students and residents, and provides administrative supervision in the maintenance of current substance abuse programs and the development of new substance abuse initiatives at Johns Hopkins. In addition to his responsibilities at Johns Hopkins, Dr. Strain has served on various study sections for NIH (and has chaired a standing study section), and he serves as the Editor in Chief for the journal Drug and Alcohol Dependence. He is on the editorial board for several other journals, and he edited, with Maxine Stitzer, the books Methadone Treatment for Opioid Dependence and The Treatment of Opioid Dependence, and with Pedro Ruiz edited the fifth edition of Lowinson and Ruiz’s Substance Abuse: A Comprehensive Textbook.

His studies have included medications such as buprenorphine, methadone and LAAM, pharmacotherapies for alcohol dependence, and non-pharmacologic treatments for substance use disorders.
