Dr. Qi Sun's research is focused on identifying novel biomarkers of diet and environmental exposures and risk of excess weight gain, type 2 diabetes, and cardiovascular disease by integrating the state-of-the-art of omics technologies and nutritional epidemiological approaches. His research has led to the discovery of endogenous metabolites (e.g., very-long chain saturated fatty acids), endocrine disruptors (e.g., bisphenol A and per- or polyfluoroalkyl substances), circulating proteins (e.g., fatty acid binding protein 4 and soluble leptin receptor), and gut microbiome as predictors or modulators of human metabolic diseases. He is also an established nutritional epidemiologist and has led numerous projects to elucidate associations between various dietary factors and cardiometabolic conditions in populations with and without diabetes. His study findings have enhanced the understanding of the biological mechanisms underlying nutrition and metabolic health and contributed to the US dietary guidelines for chronic disease prevention.
