Dr. Peter Pediaditakis joined UNC Nutrition Research Institute in 2015 as a research scientist in the N. Krupenko Lab after several years in an academic setting.  His work involves understanding how folate metabolism affects hepatocytes and how those hepatocyte effects influence the whole body. Additionally, Dr. Pediaditakis is creating specific genetic mutants in immortalized cultured hepatocytes to more clearly understand the role of the liver using metabolomics-based methods. Dr. Peter Pediaditakis received his PhD in Cellular and Molecular Pathology from the University of Pittsburgh in 2002. His thesis work was in the laboratory of Dr. George Michalopoulos where he explored the role of hepatocyte growth factor/scatter factor in liver homeostasis and regeneration. Upon completion of his doctorate, Dr. Pediaditakis joined the laboratory of Dr. John Lemasters at UNC Chapel Hill where he received an individual Ruth L. Kirschstein National Research Service Award. The focus of his post-doctoral work explored the role of protein kinases A and G in the protection of hepatocytes from mitochondrial-induced cell death. After his fellowship, Dr. Pediaditakis worked as a scientist at various institutions and private companies where he continued his work on human and mammalian hepatocyte isolation and metabolism. Dr. Pediaditakis left the laboratory for several years and taught biology, anatomy and physiology, and chemistry at both the high school and college level.
