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 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.
