Research Interests

Molecular mechanisms underlying diabetes, heart failure, and Alzheimer's disease

My current research focuses on insulin resistance associated with aging/stress-related metabolic disorders and diseases such as type 2 diabetes, diabetic cardiomyopathy, and Alzheimer’s disease. We have recently characterized a novel insulin receptor and beta adrenergic receptor network expressed in different tissues. This opens a new field to understand insulin resistance in glucose metabolism as well as in a broad range of cardiovascular complications associated with diabetes and metabolic disorders. We were able to draw recent funding from NIH and VA to support this exciting new field. One of the major goals is to understand prevalent co-existence of insulin resistance and adrenergic dysregulation in a variety of disease. We utilize a wide range of tools from single molecular analysis of receptor complexes, high resolution of living cell imaging, to in vivo genetic, surgical, and pharmacological manipulation. By combining development of novel analytical tools with in vivo and in vitro characterization of receptor signaling and function, my laboratory has developed an integrative approach to systematically analyze insulin and adrenergic signaling in the brain and peripheral tissues under physiological and disease conditions. We hope to eventually provide information/strategies on clinical therapies for different metabolic and cardiovascular conditions.
