Research Interest

As the human body continues to expand, so does the epidemic of type 2 diabetes, and novel approaches to the treatment of metabolic diseases will be needed.  My research interest involves the development of imidazoline compounds as therapeutic agents to treat metabolic disease such as type 2 diabetes.  Clinically useful imidazolines such as moxonidine have the potential to treat both hypertension and type 2 diabetes. We are interested in testing novel compounds to be used as single agent therapy for diabetics with hypertension.  We are also studying the mechanism of cross-talk between imidazoline and insulin receptor signaling pathways.
