Her primary research interest is in frailty and understanding the role of energy expenditure in the pathophysiology of aging. Using the NSHAP and Health ABC datasets her proposed research will explore an earlier marker of age-related system dysfunction: changes in energy expenditure. She hypothesizes that changes in energy utilization and regulation will reflect global deteriorations in systemic integrity and will therefore predict poor outcomes. Huisingh-Scheetz received her M.D. and M.P.H from the University of Illinois at Chicago.
