Brief Description of Research Interest:

My long term research interest lies in developing precise rehabilitation strategies to enhance age-related declines in skeletal muscle and cognitive function. I use both pre-clinical and clinical models to elucidate the molecular mechanisms underlying the beneficial effects of exercise on skeletal muscle vitality and cognitive capacity, in a geriatric population.

Currently, I am investigating the role circulating anti-geronic factors on improving skeletal muscle health and regenerative capacity of a geriatric population, in response to muscle specific resistance training protocols. In particular, I am interested in identifying mechanisms through which a pro-longevity protein called Klotho improves both, skeletal muscle regenerative capacity and cognition in an aging population. Additionally, my research focus includes studying the role of extracellular vesicles as a means to mediating such beneficial effects exercise on skeletal functional capacity and cognition of an aging population.
