Description of Research Expertise

Metabolic dysregulation has long been associated with many human diseases including heart disease, diabetes and obesity. Research in recent years has also linked disordered metabolism to cancer, stem cell function, development and almost every aspect of biology. However, how metabolism is regulated at the molecular, genomic, cellular and organismal levels is still poorly understood. Why do mature neurons use glucose exclusively while the adult heart favors fat as fuel source? Why do stem cells and many tumors prefer glycolysis while many differentiated cells exploit oxidative phosphorylation? Can we apply our knowledge of metabolism to the management of medical conditions – such as neurodegenerative disorders – not traditionally conceptualized as derangement of metabolism?
We strive to answer these questions utilizing a variety of experimental approaches from molecular and cell biology to genetics and genomics. The goal of our research is to understand metabolism and metabolic regulation in both normal physiology and disease states and apply this knowledge to human health and medicine.
