Liver and gastrointestinal physiology; gut microbiome

Geoffrey A. Preidis, M.D., Ph.D. is a board-certified Pediatric Gastroenterologist with basic research expertise in nutrition-sensitive mechanisms that regulate physiology, growth, and development. These include liver and intestinal gene regulation, enteric nervous system biology and gastrointestinal motility, bile acid homeostasis, and interactions between diet and the gut microbiome. He is actively involved in clinical and translational investigations of neonates and children with intestinal, liver, and nutritional disorders. His biomedical research career began during his undergraduate studies at Harvard University. He developed an interest in Pediatric Gastroenterology during his years in the Medical Scientist Training Program (M.D./Ph.D.) at Baylor College of Medicine. He completed internship and residency training in Pediatrics, as well as fellowship training in Pediatric Gastroenterology, Hepatology & Nutrition, at Baylor College of Medicine.
