The doctoral program prepares students for careers conducting original research in nutritional sciences in academic, governmental, health-care, or industrial settings. This degree program has two options: Nutritional Biochemistry and Physiology and Applied and Community Nutrition. Nutritional Biochemistry and Physiology - Researchers use the tools of molecular and cellular biology, biochemistry, and physiology to understand how organisms utilize nutrients to maintain optimal health. Applied and Community Nutrition - Researchers use sociological, psychological, and anthropological methods as well as education theory to investigate factors that influence the nutritional status of individuals and communities.
