Research Interests

The primary focus of my research is to investigate the lethal link between diabetes and cardiovascular disease.

Working with genetically modified mouse models associated with diabetes, my lab is applying voltage-sensitive optical imaging, conventional electrical imaging, tissue resistivity measures and measures of calcium and potassium ions to phenotype electrophysiologic changes associated with some specific aspects of diabetes, namely insulin resistance and the down regulation of glucose transport.

My lab is also studying the effects of glucose levels and insulin signaling on the electrical activity during hypoxic and ischemic conditions in Langendorff perfused isolated mouse hearts in order to characterize the direct relationship between electrical activity and glucose and insulin availability.

Please visit my lab's web page for more information.
