Janos Zempleni, Ph.D., is a Willa Cather Professor of Molecular Nutrition in the Department of Nutrition and Health Sciences at the University of Nebraska-Lincoln (UNL). His research focuses on epigenetic mechanisms by which vitamins decrease the risk for cancer and birth defects. Dr. Zempleni published 82 peer-reviewed papers and 118 review articles, books, book chapters, and symposia proceedings. He is an editorial board member of seven science journals and a regular member of grant review panels in Canada, Germany, Hungary, and the United States. He is the recipient of multiple research awards at the national and local level. John W. Suttie is the Katherine Berns Van Donk Steenbock Professor Emeritus in the Department of Biochemistry and former chair of the Department of Nutritional Sciences at the University of Wisconsin-Madison. He has broad expertise in biochemistry and human nutrition. His research activities were directed toward the toxicology of inorganic fluorides and the metabolism, mechanism of action, and nutritional significance of vitamin K. He received several research awards, and in 1996, he was elected to the National Academy of Sciences. Jesse F. Gregory III is a professor in the Department of Food Science and Human Nutrition at the University of Florida. His research has focused on the nutritional properties and metabolic function of B vitamins, especially folate and vitamin B6. Dr. Gregory is recognized for his research dealing with vitamin nutritional biochemistry, particularly the development and application of stable isotopic tracer techniques, metabolic profiling methods, and mathematical modeling to probe human metabolism. Dr. Gregory has received a number of honors including the Centrum Center for Nutrition Science Award from the American Society for Nutritional Sciences.Patrick J. Stover, Ph.D., is professor and director of the Division of Nutritional Sciences at
