Research interests


I am generally interested in the role of bioenergetic failure in disease pathophysiology. In particular, I wish to understand how mitochondrial dysfunction is involved in the pathogenesis of the Metabolic Syndrome, a cluster of medical disorders that collectively increase the risk of developing type 2 diabetes and cardiovascular disease.
