The Nutritional Genomics and Micriobiome Core is an all-encompassing support system for investigators conducting research on nutrigenetic  and microbiome aspects of obesity and obesity-related diseases.

The goal for some obesity research is to identify genetic and environmental factors and interactions that affect an individual’s susceptibility and to identify high-utility targets for prevention and treatment. In the long run, investigators should be able to individualize or personalize diet and health recommendations based on the knowledge gained from prior research conducted on obesity. Thus, there is a great need for studies with strong translational potential. Additionally, the Microbiome sub-core provides consultation (experimental design,grant writing assistance, data interpretation, and publication help) on nutrition focused microbiome studies.
