Stedman Nutrition and Metabolism Center and the Duke Molecular Physiology Institute. He develops and deploys methods for exploratory, "non-targeted" metabolomics, with emphasis on diabetes, obesity, cardiovascular disease, and health effects of the gut microbiota. His collaboration with Agilent Technologies, Inc., and Duke's Dr. Michael J. Muehlbauer has produced one of the world's largest retention-time-locked spectral libraries of metabolites for use in gas chromatography/mass spectrometry. He is especially interested in how metabolism impacts health outcomes in the perinatal period and late in life. PhD, University of Washington, Seattle, WA
