Namni Goel, Ph.D., is a Research Associate Professor in Psychiatry in the School of Medicine, University of Pennsylvania. Dr. Goel received her B.A. in Psychology and Anthropology from the University of California, Berkeley and her Ph.D. in Biological Psychology from the University of Michigan (Ann Arbor). As a graduate student, she researched the behavioral and neuroanatomical substrates underlying circadian rhythms in an animal model. As a postdoctoral fellow at Columbia and Cornell Universities, Dr. Goel made the transition to human work, conducting studies on basic human physiological sleep and on seasonal affective disorder (SAD), a mood disorder which may result from circadian rhythm pathophysiology.
Throughout her interdisciplinary career, as a broadly-trained biological psychologist and behavioral neuroscientist, Dr. Goel has been investigating individual differences in how genetic, physiological, behavioral, hormonal and environmental factors relate to resilience and vulnerability in sleep-wake functions and circadian rhythm physiology, and regulate eating behavior (including night eating), energy balance, mood and cognitive performance in humans. She also has published a substantial number of papers on circadian rhythm physiology and sleep-wake functions in animal models.
Dr. Goel’s research is currently funded by various federal agencies. As Principal Investigator, she has a major 5-year grant from the Department of Defense (Office of Naval Research), investigating candidate genes for sleep homeostasis and human neurobehavioral vulnerability to sleep deprivation. Dr. Goel is also Principal Investigator of a major 4-year grant from the National Aeronautics and Space Administration, determining the predictive validity of a set of biomarkers for distinguishing those who are more resilient versus those who are more susceptible to the adverse cognitive effects of the combination of high performance demands (including social stressors) and total sleep deprivation stressors in analog environments. She is also Institutional Principal Investigator on a grant from the National Institutes of Mental Health and a key Co-Investigator on a number of other grants from various federal agencies, including the National Institute of Diabetes and Digestive and Kidney Diseases.
In recognition of her contributions to the field, Dr. Goel was elected and served from 2008-2010 as President of the Society for Light Treatment and Biological Rhythms (SLTBR), a major international scientific organization whose membership conducts research at the interface of circadian rhythms and light and other nonpharmacological treatments for mood disorders. Since 2013, Dr. Goel has sat on the Board of Directors of the Center for Environmental Therapeutics, the leading group of international experts in chronobiological (circadian-based) treatments for mood disorders. In 2014, Dr. Goel was first author on a peer-reviewed publication on gender differences in behavioral health in space--this publication, along with others, led to the receipt of the prestigious NASA Johnson Space Center Group Achievement Award.
Dr. Goel is Vice-Chair of the Educational Programs Committee of the Sleep Research Society. In addition, she is an Academic Editor of PLoS ONE, an Associate Editor for SLEEP and a Review Editor for Frontiers in Behavioral and Psychiatric Genetics. She also serves on the Editorial Boards of four other journals (Chronobiology International, Journal of Circadian Rhythms, Journal of Neurology Research, and Journal of Sleep Disorders: Treatment and Care), and routinely reviews for a large number of scientific journals. She has been a grant reviewer for various NIH, NASA and DOD study sections and for many international granting organizations, including the Canadian Institutes of Health Research, the Wellcome Trust, the Royal Society and the Medical Research Council, among others.
