Dennis M. Bier, MD Symposium: The Future Directions of Nutrition Research - Houston, TX
A Symposium held on January 22, 2024, at the Children’s Nutrition Research Center (CNRC) celebrated the remarkable scientific career and leadership of Dr. Dennis M. Bier, a distinguished figure in pediatric endocrinology and nutrition research. Dr. Bier's journey began with his graduation from Le Moyne College and the University of Medicine and Dentistry of New Jersey, followed by fellowships at the University of California, San Francisco (UCSF) and service in the U.S. Naval Reserves. Returning to Washington University School of Medicine (WUSM), he co-directed the Division of Pediatric Endocrinology, pioneering research in mass spectrometry to explore nutrient kinetics and metabolic pathways.
Beyond the laboratory, Dr. Bier's influence extends to leadership roles at the National Institutes of Health (NIH) and directorships at WUSM and the CNRC at Baylor College of Medicine (1993-today). His commitment to mentorship and scientific rigor has propelled advancements in pediatric nutrition research. The afternoon symposium served as both a homage to his career and a critical examination of the strengths and weaknesses within the field of nutrition. Opening remarks were given by Dr. Morey Haymond and presentations by prominent researchers: Dr. David Allison, Dr. Elmquist, Dr. Christopher Newgard, and Dr. David Klurfeld. The event concluded with closing remarks from Dr. Teresa Davis, followed by a reception attended by colleagues from across the nation, honoring Dr. Bier's extraordinary career.
