The 2 X 4 Model: A Neuroscience-Based Blueprint for the Modern Integrated Addiction and Mental Health Treatment System

R. Andrew Chambers, MD is Director of Addiction Psychiatry Training at Indiana University School of Medicine in Indianapolis. He is a graduate of Centre College (chemical physics/mathematics; 1991), Duke University School of Medicine (MD; 1996), and Yale University Psychiatry (2000) and Basic Neuroscience Programs (2002). After completing the IU Addiction Psychiatry Fellowship (2012) and earning certifications in Addiction Medicine (ABAM) and Addiction Psychiatry (ABPN), Andy has practiced and taught Addiction Psychiatry at Midtown Mental Health Center in Indianapolis. His research, supported by the Veterans Administration, the American Psychiatric Association, and the National Institutes on Drug Abuse (NIDA) and Alcohol Abuse and Alcoholism (NIAAA), has pioneered rodent models of dual diagnosis, contributing to our understanding of neurodevelopmental mechanisms that drive addiction disease in adolescence and mental illness. Andy's basic, neuro-computational, and health systems research aims to translate to a better future of integrated addiction and mental health care and professional training.
