Research focus

Metabolism is known to have a critical role in the regulation of cellular homeostasis and function. Much of this regulation is dependent on the fate of intracellular metabolites within a tightly interconnected network of reactions. In our lab, we use state-of-the-art technology of metabolic flux analysis to identify the mechanisms regulating the metabolic fate of intracellular metabolites and to understand how they impact cellular function. We primarily develop metabolically targeted approaches to improve the function of pancreatic beta-cells but we are also very much interested in applying this approach to models of stem cell differentiation, cancer and immunology.
