Zeisel_Photo.jpgSteven Zeisel, M.D., Ph.D.
Professor, Department of Nutrition, Director, Nutrition Research Institute and Nutrition Obesity Research Center, University of North Carolina

Dr. Zeisel is the Kenan Distinguished University Professor in the Department of Nutrition in the Gillings School of Global Public Health and School of Medicine at the University of North Carolina at Chapel Hill. Dr. Zeisel earned his MD from Harvard Medical School in 1975, was a resident in pediatrics at Yale University from 1975–1977 and earned his PhD in nutrition at the Massachusetts Institute of Technology in 1980. He served as chair of the Department of Nutrition at UNC from 1990–2005. Dr. Zeisel is the Director of the UNC Nutrition Research Institute and Director of the UNC Nutrition and Obesity Research Center (one of 12 centers of excellence funded by the US NIH), North Carolina. He serves on the Federation of American Societies for Experimental Biology (FASEB) Journal editorial board. He is an international leader in the development of the field of precision nutrition. Dr. Zeisel and his research team focus on the essential nutrient choline and why there are individual differences in nutrient metabolism, using new approaches in nutrigenetics, epigenetics and in metabolomics. The team works with humans, mice and cell culture model systems. We are currently conducting clinical studies to develop better biomarkers for choline status; choline is an important essential nutrient.  In our human studies, we discovered that there are very common single nucleotide polymorphisms (SNPs; gene misspellings) that make humans require more dietary choline. Some are especially important during pregnancy, some affect risk for fatty liver, some for muscle breakdown during exercise (rhabdomyolysis), some for liver cancer risk and some for sperm dysfunction. Another important focus for the Zeisel lab is understanding how choline influences brain development.  We discovered that choline is critical for cortical and hippocampal development. We used mouse models and neural progenitor cells in culture to identify the molecular mechanisms for choline’s effect on brain and identified the underlying epigenetic (miRNA) mechanisms. Based on his research, the US Institute of Medicine set a dietary requirement for choline in 1998 and the FDA revised the regulations for formulation of all infant formulas so that they contain adequate choline in 2007. Dr. Zeisel has authored more than 370 scientific publications.
