Research interests

Research conducted by my laboratory is focused on the regulation of lipid metabolism, predominantly fatty acid storage and utilisation, and how this may be perturbed in chronic disease states such as cancer, obesity and insulin resistance. For example, investigations are underway to understand the relationship between lipid and glucose metabolism and insulin action. A role for dysregulation of lipid metabolism, which results in accumulation metabolically active lipid intermediates, has been shown to interfere with insulin signalling. Investigations into the relationship between the main site of fatty acid storage, the lipid droplet, and the mitochondria and how this maybe hormonally regulating are ongoing. Finally, understanding the potential role for altered fatty acid metabolism in cancer is another stream of research.
