Dr. Wehby is a health economist and a health services researcher. His research focuses on studying socioeconomic, healthcare, behavioral, and policy 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 is also interested in the interplays between child health and educational achievement. Dr Wehby has also completed several national and international studies on racial and socioeconomic disparities in child health and development. He also works on 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 directs the doctoral program and teaches courses in health economics and health services research methods.
Dr. Wehby holds secondary appointments in the Department of Economics, Public Policy Center and the Department of Preventive and Community Dentistry.
