Dr. Michel Baum received his BS and MD degrees from the University of California at Los Angeles. He performed his internship and residency at Yale University School of Medicine and his fellowship in nephrology at the University of California at San Francisco, where he was a research fellow at the Cardiovascular Research Institute. Since completion of his fellowship he has been at UT Southwestern Medical Center , where he is a Professor of Pediatrics and Internal Medicine, and Children’s Medical Center of Dallas. He also holds the Sara M. and Charles E. Seay Chair in Pediatric Research.

Dr. Baum is a member of a number of national societies including the American Society for Clinical Investigation, the Association of American Physicians, the Society for Pediatric Research, and the American Society of Nephrology and International Pediatric Nephrology Association. He has served as a member of the General Medicine B Study Section and the DDKD Study Section for the NIH. Dr. Baum’s research primarily examines the maturational changes that occur in renal tubular transport during development. He has described many changes in transporters that explain the physiologic difference between the neonatal kidney and the adult kidney. His other research interests include the pathophysiology and pathogenesis of hereditary defects in tubular transport such as X-linked hypophosphatemia. He is also investigating the cause for hypertension inpatients with a prenatal insult that are small for gestational age. His research is funded by the National Institutes of Health. He has contributed to more than150 publications.
