Faculty Profile

Dr. Jonathon (Jack) Senefeld earned a BS in Exercise Physiology and a PhD in Clinical and Translational Rehabilitation Health Sciences— both from Marquette University. Following his PhD, he completed postdoctoral research fellowships at Marquette University (2018 to 2019) and Mayo Clinic (2019 to 2021). Dr. Senefeld’s research program focuses on advancing the understanding of nonpharmacological interventions (such as exercise) to mitigate the detrimental effects of human aging and metabolic diseases. Specifically, Dr. Senefeld’s research program is interested in how skeletal muscle fatigue negatively influences exercise responses in older adults and people with diabetes, as well as how exercise training might improve these impaired responses. Dr. Senefeld’s research program is also interested in how sex-specific mechanisms contribute to the etiologies of muscle fatigue and the physiological processes that limit human performance.
