James M. Swanson, Ph.D., is a professor of pediatrics at the University of California, Irvine, School of Medicine, and the founding director of the UC Irvine Child Development Center. He received his doctorate in psychology from Ohio State University. His research focuses on attention deficit hyperactivity disorder (ADHD). Through his research, Dr. Swanson has developed procedures for monitoring the cognitive effect of stimulant medication, the most frequent treatment for this group of patients. He also investigates biochemical and genetic factors related to ADHD. He has developed clinical treatment programs based on intensive behavioral intervention for children with ADHD and related disorders in a school-based treatment program. In addition, he is an investigator in long-term follow-up studies to evaluate the risk and protective factors for adverse outcomes of ADHD children as they mature. Dr. Swanson’s work has been supported by research grants from the National Institutes of Health. Dr. Swanson is the principal investigator of the Orange County Vanguard Center and the Southern and Central California Study Center of the U.S. National Children’s Study (NCS), that is in the pilot phase and is intended to be one of the largest and most comprehensive studies of genetic and environmental influences on child development and health.
