Dr. Richard J. Haier is Professor Emeritus in the School of Medicine at the University of California, Irvine, where he has been teaching and conducting research since 1984. He earned his B.A. in Psychology from the State University of New York at Buffalo, and his Ph.D. in Psychology from Johns Hopkins University. Before his appointment at Irvine he was on the faculty of Brown University’s Alpert Medical School.
Professor Haier’s main research interest is the structural and functional neuroanatomy of higher cognitive processes, especially intelligence. In 1988, he and his colleagues conducted the first modern functional brain imaging study of intelligence with positron emission tomography (PET) and proposed a hypothesis linking good performance on an intelligence test to efficient brain function. Professor Haier’s more recent research with magnetic resonance imaging (MRI) has identified specific brain areas where gray and white matter features correlate to the g factor of intelligence and other intelligence factors. In 2012, he received the Distinguished Contributor Award from the International Society for Intelligence Research.
In addition to his many professional publications, Professor Haier’s research has been featured on NOVA scienceNOW, NPR, CNN, and CBS Sunday Morning, and in numerous newspaper and magazine articles.
