Research Description: 

Dr. Witkowski's research interest is in conventional and novel risk factors for cardiovascular disease and how they are influenced by physical activity, physical inactivity, and exercise. Recent research involves investigations of markers of cardiovascular disease such as endothelial dysfunction and adult stem cells known to contribute to the maintenance, regeneration, and repair of the vascular endothelium. Dr. Witkowski and her lab are interested in understanding how these tissues are influenced by detrimental environments such as pro-inflammatory and hyperglycemic states and the mechanisms by which changes in physical activity behavior may alter the function of these tissues. Understanding the contribution of these tissues to cardiovascular health will help us understand cardiovascular disease and lead to optimization and personalization of prevention and treatment.
