RESEARCH INTERESTS

Metabolic flexibility allows for the adaptation of fuel oxidation to fuel availability. A decreased ability to switch between usage of lipids and carbohydrates is often seen in patients with obesity and type 2 diabetes mellitus. Our laboratory has used data from translational studies involving models of metabolic flexibility and inflexibility in both mice and humans in order to identify important molecular controls of substrate sensing and utilization. Our laboratory is currently interested in determining the way in which proper control of cellular RNA levels by the RNA binding protein, HuR, ensures maintenance of metabolic flexibility.
