Research Interests
Dr. Zou’s ongoing research programs look at the means to sense oxidative stress, reduce it, or ameliorate the body’s adverse response to it. Dr. Zou has been instrumental in examining the role of nitric oxide and oxidative stress in the regulation of blood flow and vascular function. He performed elegant, state of the art, studies to show that the selective modification of two key proteins, prostacyclin synthase and endothelial nitric oxide synthase, is critical in the dysregulation of vessel function from nitric oxide and superoxide. Dr. Zou’s research group was also the first to demonstrate that the AMP-activated kinase (AMPK), a key enzyme in the regulation of energy metabolism, obesity, diabetes, and cardiovascular diseases, functions as a sensor and regulator of oxidative stress. Dr. Zou’s contributions in this area are important and his work represents outstanding breakthroughs in research which have been recognized by many other investigators in the field. Dr. Zou is an independent investigator of the National Institutes of Health and the Juvenile Diabetes Research Foundation International (JDRF) and a National Scientist Development awardee of the American Heart Association. Dr. Zou has used these (and many other awards) to make scientific observations in the field with great potential for immediate clinical relevance. He has served on several national study panels such as the National Institutes of Health and American Heart Association. In 2008 he was elected to the American Society for Clinical Investigation, membership in which reflects accomplishments by its members at an early stage in their careers and one of the United States’ oldest honor societies of physician-scientists.
