Robert Andrew Chambers
R. Andrew Chambers, MD, is a neuroscientist, educator, and clinician in the field of addiction psychiatry. Andy’s research has investigated the brain anatomy and neural mechanisms that fundamentally link the pathologies of addiction and mental illness. This research translates into the design of a new behavioral health system called the 2 x 4 Model which aims to achieve full integration of addiction and mental health treatment services, professional training, and clinical research.
Biography
R. Andrew Chambers is Associate Professor of Psychiatry, and Director of Addiction Psychiatry Training at Indiana University School of Medicine, in Indianapolis. He is a graduate of Centre College (1991:B.S., chemical physics/mathematics), Duke University School of Medicine (1996: M.D.), and the Yale University Psychiatry Residency (2000) and Fellowship Programs in Basic Neuroscience (2002). His career development and research have been supported by grants from the National Alliance for Research on Schizophrenia and Depression, the Veterans Administration, the American Psychiatric Association, and the National Institutes on Drug Abuse (NIDA) and Alcohol Abuse and Alcoholism (NIAAA). He completed his Addiction Psychiatry fellowship at IU in 2012, earning certifications in both Addiction Medicine (ABAM) and Addiction Psychiatry (ABPN). He practices Addiction Psychiatry in the Adult Dual Diagnosis Clinic at Midtown Mental Health Center, Indianapolis, and has served as an expert consultant for the Attorney General of Indiana and the U.S. Drug Enforcement Administration. As Director of the Addiction Psychiatry Program at IU, Andy leads physician training in psychiatric addictionology at the nation’s largest medical school. As Director of the Laboratory for Translational Neuroscience of Dual Diagnosis and Development at IU, Andy’s research has pioneered the use of rodent models of dual diagnosis, and new theory design in exploring the neurodevelopmental mechanisms that drive addiction disease in adolescence and mental illness. His work, spanning animal modeling, neurocomputational, clinical, and health systems research has contributed to building a neuroscientific foundation, and clinical translation upon which fully integrated addiction and mental health services and professional training of the future may be built.Education

On Mourning and Recovery: Integrating Stages of Grief and Change Toward a Neuros

The article explores addiction as a form of pathological attachment. Prochaska's Stages of Change and Kubler-Ross's stages of Grief may be complimentary and overlapping manifestations of a more general neural network adaptation that has to happen in the course of successful recovery from addiction.
Nicotine is more addictive, not more cognitively therapeutic in a neurodevelopme

This is the first animal modeling experiment demonstrating nicotine addiction vulnerability in a neurodevelopmental animal model of mental illness.
A Scale-Free Systems Theory of Motivation and Addiction

Authors: R. Andrew Chambers, M.D.,corresponding author Warren K. Bickel, Ph.D., and Marc N. Potenza, M.D., Ph.D.
Motivated behavior in Addiction disease can be understood computationally as an informatic map, generated by striatal neural networks, of motivational links connecting behavioral nodes. Dopamine mediated plasticity sculpts these maps for organizational efficiency and behavioral adaption in a way that can be pathologically influenced by mental illness or adolescent neurodevelopment in the course of addictive disease.
Developmental Neurocircuitry of Motivation in Adolescence: A Critical Period of
Published: Jun 01, 2003 by American Journal of Psychiatry

As informed by the neurocircuit basis for addiction vulnerability in mental illness (Chambers et al. Biol Psy, 2001) the neurodevelopmental changes of adolescence can also be appreciated as a vulnerability state that accelerates addiction pathogenesis.
A Neurobiological Basis for Substance Abuse Comorbidity in Schizophrenia

Authors: R. Andrew Chambers, John H. Krystal, and David W. Self
First description of a neuroscientific basis of addiction acceleration in mental illness presented as an alternative to the self-medication dogma.

Schizophrenia and other major mental illnesses produce an involuntary, brain-based vulnerability to nicotine, cocaine, alcohol and opioid addictions. This neuroscience questions the wide gap between mental health and addiction training, services and research, and translates to a new approach to integrated behavioral health care called the '2 x 4 Model'.
