Pathik D. Wadhwa, M.D., Ph.D., is a professor at the University of California, Irvine, School of Medicine, with a primary appointment in psychiatry and human behavior and joint appointments in obstetrics and gynecology, pediatrics, and epidemiology. Dr. Wadhwa also is the founding director of the UC Irvine Development, Health and Disease Research Program. He received his medical degree from the University of Pune, India, in 1985, and his doctorate in behavioral medicine from the University of California, Irvine, in 1993. He studies the interface between biological, social, and behavioral processes in human pregnancy, with an emphasis on outcomes related to fetal development, birth, and subsequent newborn, infant, and child development and health. In particular, this work focuses on maternal-placental-fetal neuroendocrine, immune, and genetic processes as putative mechanisms that mediate the effects of the maternal environment (and particularly prenatal stress) on early human development. Dr. Wadhwa’s work has been supported by research grants from the National Institutes of Health. Dr. Wadhwa also is the co-investigator of the Orange County Vanguard Center of the U.S. National Children’s Study (NCS), which is conducting a pilot work for the future main study that is intended to be one of the largest and most comprehensive studies of genetic and environmental influences on child development and health.
