George Wehby, Ph.D.
Dr. Wehby is trained as a health economist and health services researcher. His research focuses on studying the socioeconomic, healthcare, and behavioral determinants of health, especially child health, and the long term effects of early life conditions on health and human capital, using econometric methods. Dr. Wehby has conducted several studies that evaluated the effects of prenatal care, maternal health behaviors, and household investments on early child health and development. He has also completed several national and international studies on racial and socioeconomic disparities in child health. Furthermore, Dr. Wehby is interested in interdisciplinary studies that integrate genetics and social sciences and has pioneered several studies that use genetic information for identifying causal prenatal behavior effects on child health. Dr. Wehby has a very active externally funded research program and has received several NIH and CDC grants. Dr. Wehby teaches courses in health economics and health services research methods.
