Liza A PonLiza A. Pon, PhD, is a Professor of Pathology and Cell Biology and the Institute of Human Nutrition, and Director of the Confocal and Specialized Microscopy Shared Resource at Columbia University. As a PhD student at Tufts University, she carried outthe first characterization of a protein now known as StaR, steroidogenic acute regulatory protein, which mediates transfer of cholesterol within mitochondria during steroid hormone biosynthesis. As a post-doctoral scientist with Gottfried (Jeff) Schatz at the University of Basel, she studied the mechanism of import of proteins into mitochondria. Dr. Pon joined Columbia University in 1990 and has been there ever since. Her research focuses on mitochondrial motility, dynamics, quality control and interactions with other organelles, and how these processes affect cell cycle progression, cellular fitness and lifespan. Recent studies in the laboratory focus on mechanisms for detection and removal of unfolded and damaged proteins not just in mitochondria but also in the ER in models of aging and disease.
