Dr. Sumner is a Professor in the Department of Nutrition at the University of North Carolina at Chapel Hill (UNC-CH), where she is working to make Precision Nutrition a reality.  Her team uses untargeted analysis to detect tens of thousands of signals in biospecimens that represent the internal exposome of endogenous and exogenous metabolites. This research is key to informing precision nutrition through understanding how exposures, and perturbations in endogenous metabolism, are linked to states of health and wellness. Through this approach, biomarkers are discovered that can lead to new diagnostics for the early detection and diagnosis of disease, to monitor treatment and intervention, and to reveal metabolic perturbations that inform the development of intervention strategies. Dr. Sumner earned a PhD in physical chemistry at North Carolina State University, and conducted a postdoctoral fellowship in the Heart, Lung, and Blood Institute at the National Institutes of Health. She serves on the Editorial Boards for Frontiers in Nutrition, and Metabolomics. She was elected two terms to the Board of Directors of the Metabolomics Society.
