Heather M. Gray, PhD

Dr. Heather M. Gray is Director of Academic Affairs at the Division on Addiction, Cambridge Health Alliance, a Harvard Medical School Teaching Hospital, and an Instructor in Psychiatry at Harvard Medical School. She received her PhD in social psychology from Harvard University in 2006 and completed a post-doctoral fellowship with the Boston University Health and Disability Research Institute.

Dr. Gray joined the Division during 2008. She has collaborated with her Division colleagues to study the development of, and recovery from, addictive disorders. In particular, she has studied how social networks and personal identities relate to alcohol and other drug use behavior. She has completed program evaluation to document how people change their lives after completing substance use disorder and wellness interventions. In collaboration with Internet and land-based gambling operators in the US and internationally, Dr. Gray has studied how people gamble and respond to interventions designed to promote responsible gambling.

In her role as Director of Academic Affairs at the Division, Dr. Gray serves as Course Director of our annual live course, Addiction Medicine: A Case-based Approach. She also serves as Course Director for a Harvard Medical School online CME course, Gambling Disorder in Your Practice: Information and Resources. This course aims to provide non-specialists with tools for assessing and responding to gambling disorders among their patients. Dr. Gray serves as the Senior Editor of The BASIS (The Brief Addiction Science Information Source). She encourages others to help advance the Division’s mission by coordinating the Division’s Undergraduate Summer Mentorship and Visiting Scholars programs, which bring undergraduate students and researchers to the Division to become partners in our ongoing research projects.
