George F. Koob (born 1947) is a Professor and former Chair of the Committee on the Neurobiology of Addictive Disorders at the Scripps Research Institute[1] and Adjunct Professor of Psychology, Psychiatry, and Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California, San Diego. In 2014 he became the director of the National Institute on Alcohol Abuse and Alcoholism.[2]
Koob holds a B.S. in zoology from Pennsylvania State University (1969) and a Ph.D. in Behavioral Physiology from the Johns Hopkins Bloomberg School of Public Health (1972). Subsequently he was a post-doctoral fellow at the University of Cambridge.
An authority on addiction and stress, Koob has published over 750 scientific papers and has received continuous funding for his research from the National Institutes of Health, including the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA). He was, until 2014, the Director of the NIAAA Alcohol Research Center at the Scripps Research Institute, Consortium Coordinator for NIAAA's multi-center Integrative Neuroscience Initiative on Alcoholism, and Co-Director of the Pearson Center for Alcoholism and Addiction Research. He has trained 10 predoctoral and 64 postdoctoral fellows. Koob is the former Editor-in-Chief for the journal Pharmacology Biochemistry and Behavior and for the Journal of Addiction Medicine. He won the Daniel Efron Award for excellence in research from the American College of Neuropsychopharmacology, was honored as a highly cited researcher from the Institute for Scientific Information, was presented with the Distinguished Investigator Award from the Research Society on Alcoholism, and won the Mark Keller Award from NIAAA. He published a landmark book in 2006 with his colleague Michel Le Moal entitled: Neurobiology of Addiction (Academic Press-Elsevier, Amsterdam).
His research interests continue to be directed at the neurobiology of emotion, with a focus on the theoretical constructs of reward and stress with a specific interest in understanding the neuroanatomical connections comprising the emotional systems and neurochemistry of emotional function. During the past 3 years, his work has been focused on the role of the extended amygdala (medial shell portion of the nucleus accumbens, bed nucleus of the stria terminalis, and central nucleus of the amygdala) in behavioral responses to stress, the neuroadaptations associated with drug dependence, and compulsive drug self-administration.
Koob's work on the neurobiology of stress has included the characterization of behavioral functions in the central nervous system for catecholamines, opioid peptides, and corticotropin-releasing factor. Corticotropin-releasing factor, in addition to its classical hormonal functions in the hypothalamic-pituitary-adrenal axis, is also located in extrahypothalamic brain structures and may play an important role in brain emotional function. Recent use of specific corticotropin-releasing factor receptor antagonists suggests that endogenous brain corticotropin-releasing factor may be involved in specific behavioral responses to stress, the psychopathology of anxiety and affective disorders, and drug addiction. He has also characterized functional roles for other stress-related neurotransmitters/neuroregulators, such as norepinephrine, vasopressin, hypocretin (orexin), neuropeptide Y, and neuroactive steroids.
In the domain of drug addiction, Koob's past work contributed significantly to our understanding of the neurocircuitry associated with the acute reinforcing effects of drugs of abuse. More recently, the focus has been on the neuroadaptations of these reward circuits and the recruitment of the brain stress systems during with the transition to dependence. To this end, he has validated key animal models for dependence associated with drugs of abuse and has begun to explore a key role of anti-reward systems in the development of dependence. The neurotransmitter systems in the extended amygdala under current investigation include corticotropin-releasing factor, norepinephrine, dynorphin, orexin, neuropeptide Y, and the sigma receptor system.[2]
Finally, Koob's recent contributions include scholarly treatises on the conceptual framework and theoretical bases for understanding the neurobiology of drug addiction. He has contributed key reviews on the “dark side of addiction” in very prominent journals in the field, including Annual Review of Psychology, Nature, Neuron, and Neuropsychopharmacology, and Nature Reviews Drug Discovery.
After reports broke that members of NIAAA staff had approached the alcohol industry for the purpose of funding a study into moderate drinking, an investigation was conducted that identified the conduct occurred prior to Koob's tenure.[3] [4] [5] Koob expressed disapproval at the ethically-compromised study, and canceled it in June 2018,[6] while the investigation exonerated him of wrongdoing.[7]
