Dr. Preidis is a physician-scientist at Baylor College of Medicine and Texas Children’s Hospital, where he is clinically trained in pediatric gastroenterology, hepatology, and nutrition. His laboratory seeks to to define mechanisms through which early life undernutrition alters metabolism and to determine how undernutrition influences intestinal and liver function. Undernutrition causes acute medical problems, but also long term health problems that may result from permanent epigenetic changes that alter transcription or via changes in the gut microbiome. Current studies focus on how malnutrition alters hepatic secretion, transcriptional programming, gastrointestinal motility, and host-microbiome interactions to impact growth. His laboratory's work is pertinent to those suffering from nutritional deficiencies caused by a wide range of medical and socioeconomic factors, including protein-energy undernutrition in the developing world and underweight newborns in the neonatal intensive care unit.

Dr. Preidis is the recipient of funding from the National Institutes of Health, Global Probiotics Council, Thrasher Research Fund, North American Society for Pediatric Gastroenterology, Hepatology and Nutrition Foundation/Nestle Nutrition Research, Texas Medical Center Digestive Disease Center, Alkek Center for Metagenomics and Microbiome Research, American Neurogastroenterology and Motility Society, American Gastroenterological Association-Rome Foundation, and Ting Tsung and Wei Fong Chao Foundation. His most recent work is published in PLoS Neglected Tropical Diseases, Journal of Nutritional Biochemistry, Journal of Nutrition, Therapeutic Advances in Gastroenterology, Gut Microbes, and Journal of Clinical Investigation.

Dr. Preidis received his A.B. from Harvard University in 2003, his Ph.D. in Translational Biology and Molecular Medicine from Baylor College of Medicine in 2011, and his M.D. from Baylor College of Medicine in 2012.
