Biography

Samantha Pritchard, PhD, RD, LDN, is a Chicago-area native and joined Rush University in 2019. In the Department of Clinical Nutrition, she teaches courses in macro- and micronutrient metabolism, and has a weekly appointment in the Rush Cancer Center, providing nutrition education to patients in the Chest Tumor Clinic. Pritchard earned a bachelor’s degree in Dietetics from Iowa State University (ISU), and then spent three years as a Clinical Oncology Dietitian in suburban Chicago. She returned to ISU to pursue a PhD in Nutritional Sciences where her research focused on dietary intervention strategies to maintain vitamin D homeostasis in animal models of diabetes and inflammatory bowel disease. As a Post-Doctoral Fellow at the University of Minnesota Medical School, she was appointed to the National Institutes of Health Institutional Training Grant (T32) in Diabetes, Endocrinology, and Metabolism, where her studies explored the developmental origins of pancreatic beta cell dysfunction.
