We study the regulation of metabolism in excitable cells including skeletal muscle, brain and heart.  Our particular focus is on skeletal muscle because its physiologic function is well defined, easily measured and it dictates the metabolic responses through the demand for ATP.   Our musculature is the largest organ system in the body comprising 40-45% of body mass in the average adult and is important in glucose homeostasis.  Understanding metabolic flux, substrate utilization and mitochondrial function are critical to resolve the pathophysiology associated with metabolic diseases such as diabetes and metabolic syndrome.   Our laboratory uses magnetic resonance imaging and spectroscopy to non-invasively measure blood flow, perfusion and energy dynamics respectively.   We also use a host of computational and biophysical techniques from mathematical modeling to high resolution respirometry, genetic modifications in transgenic animals, and viral vectors to induce metabolic challenges in host animals.
