UNC Nutrition Obesity Research Center (NORC)
Metabolomics and Exposome Core


The Metabolomics and Exposome Core provides cutting edge nutritional metabolomics services, biochemistry methods and molecular biology techniques for nutrition research.

The goals of our Core are to encourage and facilitate the use of biomarkers for nutritional epidemiological and intervention studies, to provide access to state-of-the-art techniques and equipment to bench scientists, and to provide cost-effective assays for investigators without lab facilities. The Core also provides training for students and postdoctoral fellows. This Core is split between two locations, one at Chapel Hill and one at Kannapolis. This way we are able to provide a wide array of instrumentation and support investigators at either location.

Additionally, metabolomics, the profiling of the many small molecules in blood, urine or tissues, provides an opportunity for investigators to obtain a snapshot of metabolism. The metabolomics lab, located in Kannapolis, NC, is working to make personalized medicine a reality through metabolomics. Metabolomic analyses provide a more comprehensive view of a patient’s metabolism than the limited measurements of glucose and cholesterol that doctors employ today. Using metabolomics, the lab assesses differences in the metabolic profile of individuals that correlate with states of wellness or disease.
