Research interests: 
I have been interested in various aspects of diabetes research for the past 25 years. My laboratory has investigated insulin binding and action in isolated tissues and cells. Currently, I am studying the possibility of delivering insulin and other peptide drugs at therapeutic levels using ocular, nasal or oral formulations containing novel absorption-enhancing agents. A patent has been issued on this work and a license has been signed with a biotech firm to bring this product to market. In addition to this primary line of research, I have participated in diabetes education programs in urban and rural settings where health care delivery to persons with diabetes mellitus was lacking. I serve on several public service committees dedicated to diabetes advocacy and I play a leaderhip role in diabetes education and advocacy in the State of Alabama and nationally.
