My primary interests are determining the impact of oxidative stress on vascular function and blood flow regulation in healthy and diseased populations. Within this focus my research interests are numerous as my laboratory examines the relationship between oxidant-antioxidant balance and vascular health in various populations such as fit and unfit young adults, older adults, and individuals possessing mental health disorders (e.g. PTSD, generalized anxiety disorder) or undertaking negative lifestyle behaviors (sedentary activity, poor sleep, poor diet). Moreover, we utilize numerous interventions to evaluate vascular function/adaptation and blood flow regulation such as acute and chronic exercise (small and large muscle mass), nutraceuticals supplementation (vitamin C, MitoQ, folic acid), prolonged sedentary behavior, and high salt intake.
