Xiaobin Wang, M.D., M.P.H., Sc.D., is Zanvyl Krieger Professor in Children’s Health and director of the Center on the Early Life Origins of Disease at the Johns Hopkins University Bloomberg School of Public Health, professor of pediatrics at the Johns Hopkins University School of Medicine, and an American Board of Pediatrics–certified pediatrician at The Johns Hopkins Hospital. In the past two decades, Dr. Wang has served as the principal investigator for more than a dozen large-scale molecular epidemiological studies funded by NIH. She has led multi-institution, multidisciplinary teams to conduct large-scale prospective birth cohort studies to investigate environmental and nutritional factors and genetic, epigenetic, and metabolomic biomarkers during critical developmental windows (e.g., in utero, early childhood) in relation to the life course and intergenerational health in diverse populations. For example, Dr. Wang established the Boston Birth Cohort, one of the largest and longest birth cohorts of a U.S. urban, low-income, minority population with multilevel and longitudinal data collection; the cohort has already contributed more than 100 peer-reviewed publications. Those studies have advanced our understanding of early-life precursors of pediatric and chronic diseases, including preterm birth, food allergies, asthma, autism, ADHD, obesity, diabetes, and hypertension. Dr. Wang is an elected member of the National Academy of Medicine.
