Sergey A. Krupenko, PhD, joined the UNC Nutrition Research Institute in 2014. Dr. Krupenko’s research focuses on vitamin folate and its role in liver function and cancer disease. His goal is to understand how we can fight cancer by controlling the diet and nutrient supplements. “There are molecular strings in the human organism, which can be pulled by the right combinations of nutrients to activate resistance to tumor formation or to slow down cancer development. We have to identify these links and make them work,” he said. Dr. Krupenko has received his Bachelor’s Degree in Biochemistry from Byelorussian State University and a PhD in Biochemistry at the Byelorussian Academy of Sciences. Before joining the NRI, he was a faculty member in the Department of Biochemistry, Vanderbilt University School of Medicine, and in the Department of Biochemistry and Molecular Biology, Medical University of South Carolina. He has a joint appointment as a Professor of Nutrition at the Gillings School of Global Public Health, UNC-Chapel Hill.
