Shannon Galyean joined the Nutritional Sciences department in 2018 and began working as Interim Director at Nutrition and Metabolic Health Initiative in 2024.
Shannon has professional experience in the field of dietetics as a registered dietitian nutritionist since 2001. Most of her practice focused in the areas of obesity management, vitamin/mineral deficiencies, and bariatric surgery. She has also worked in many fields of dietetics such as renal, diabetes, cardiac, pediatric, geriatric, and enteral nutrition.

Research Focus
- Precision nutrition and micronutrient/vitamin D metabolism
- Nutrigenetics, dose response, and bone mineral density
- Gut microbiome and use of synbiotic supplementation
- Nutrition interventions and the effects on blood pressure and type 2 diabetes
- Culinary medicine
- Increased vegetable consumption
Research Interests or Areas of Expertise
Shannon has conducted studies among people with chronic conditions (cardiometabolic disease, diabetes mellitus, high blood pressure, and obesity) to find strategies to improve nutritional management of chronic conditions, access to care, and patient empowerment. She is looking for innovative ways to involve nutrition that can improve health outcomes in people with chronic diseases.
Shannon has also investigated obesity, bariatric surgery, and health in senior adults and the association with the gut microbiota and decreased micronutrient status as well inflammation and immunometabolism among people with severe obesity. She has conducted studies probiotics/synbiotics and nutrition interventions to determine the effects on gut health and muscle quality among adult and senior populations.
Additionally, Shannon is CRO and co-founder of 3 CulinaryMed Docs that created sam, a culinary medicine app that develops personalized, medically tailored meal plans for people with multiple chronic conditions. She led multiple studies involving the use of this app as a person-centered approach to improve health outcomes among people with chronic conditions.
