The Center for Addiction Medicine has pulled together a team with the complementary skills and expertise needed to fulfill the mission of the center. We are psychiatrists, neuropsychologists and neuroscientists with a background in clinical trials, neuroimaging and cognitive neuroscience. Faculty, post-docs, and staff work together to study the causes of and test new treatments for addictive disorders. The faculty and fellows have appointments at both Harvard Medical School and the Massachusetts General Hospital.
