Insulin signaling, Insulin resistance, Metabolism
My research interests are focused on the regulation of metabolism by hormones and nutrients, with a particular emphasis on the master regulators of organismal metabolism, insulin and glucose. Alterations in insulin and glucose signaling underlie metabolic disease and lead to the development of deadly vascular and neuronal complications. Through the use of various techniques encompassing molecular biology, biochemistry, metabolomics, genome-wide transcriptional techniques and whole-animal physiology, the long-term goals of my research program are to decipher the underlying mechanisms driving metabolic deregulation during disease and identify new therapies that improve metabolic control.
