Dr. Shannon Galyean, Ph.D., RDN, LD


Shannon Galyean is a PhD, RDN, LD and assistant professor in the Nutritional Sciences department at Texas Tech University. She is also a clinical dietitian at Texas Tech University Nutrition & Metabolic Health Initiative. After completing her training in dietetics, she has practiced as a clinical dietitian since 2001. She began working in the field of bariatric surgery in 2004 and gained a great interest in improving the microbiome, bile acid metabolism, and hormonal changes following bariatric surgery. Another interest that developed while working in bariatric surgery was nutrient deficiencies and looking for new and innovative delivery methods for nutrients.

Dr. Galyean has had a long-standing work relationship with a bariatric surgeon as well as work experience in cardiac, diabetes, renal, enteral nutrition, pediatric, geriatric, and weight management.

She has taught many graduate courses including Bariatric Nutrition, Clinical Applications: Vitamins and Minerals, Obesity Management for the Clinical Practitioner, as well as an undergraduate course, the Science of Nutrition.

As a practitioner, she has published in the area of inflammation and obesity. She conducted studies with bariatric surgery patients involving vitamin D supplementation as well as collecting human tissue samples to study visfatin/nicotinamide, phosphoribosyltransferase (nampt), retinol binding protein-4, and vaspin concentrations and insulin resistance in severely obese subjects. She has recently conducted research with bariatric surgery patients and the use of a multivitamin and mineral patch to determine the efficacy of vitamin and mineral absorption after bariatric surgery via transdermal application in comparison to oral formulations. Working in the research areas of obesity and chronic diseases, with a focus in bariatric surgery, is of great interest to her.
