Research Interests: Dr. O’Connor has focused his research on the interface between primary care and addiction medicine. This has included research examining the transfer of addiction treatment strategies from “specialty” settings to primary care and other general medical settings. His publications in this area include studies on the management of opioid withdrawal in primary care settings, opioid maintenance in primary care, and the use of naltrexone for treating alcohol dependence in primary care patients. He has been active in medical education on addiction both nationally and internationally and has served as the President of The Association for Multidisciplinary Education and Research on Substance use and Addiction (AMERSA) and of the American Board of Addiction Medicine (ABAM) and The Addiction Medicine Foundation.
