Gary R. Berntson, a founding father of the field of social neuroscience, is a professor at The Ohio State University with appointments in the departments of psychology, pediatrics, and psychiatry. He studies the functional organization of brain mechanisms underlying behavioral and affective processes, with a special emphasis on social cognition. A graduate of the University of Minnesota, where he earned his undergraduate degree and took a Ph.D. in psychobiology and the life sciences in 1971, he held a National Science Foundation (NSF) postdoctoral fellowship at Minnesota and subsequently a NSF and United States Public Health Service postdoctoral fellowship at Rockefeller University. Dr. Berntson joined the Ohio State psychology faculty as an assistant professor in 1973 and was appointed a full professor in 1982. The next year he was named a professor of pediatrics and, in 1988, a professor of psychiatry. From 1984 to 1995, he also was an affiliate scientist at the Yerkes Regional Primate Research Center at Emory University. He has been a visiting professor at the University of Chicago. His research is supported by the National Institute of Mental Health, the National Institute of Child Health and Human Development, the National Institutes of Health, the National Science Foundation, the National Heart, Blood, and Lung Institute, the March of Dimes, the Ohio Heart Association, the University of Chicago, and the John Templeton Foundation. A fellow of the American Psychological Society, the International Organization for Psychophysiology, and the American Association for the Advancement of Science, Dr. Berntson has received distinguished teaching awards from Ohio State and special recognition for his scholarship from the Ohio House of Representatives. He is the president-elect of the Society for Psychophysiological Research. The co-editor of the Social Neuroscience Book Series for MIT Press, he currently serves on the editorial board of the International Journal of Psychophysiology.
