My primary interest is in prevention of age-related diseases and the promotion of successful aging. The research in my laboratory is centered on redox biology of aging and the role of exercise and phytonutrients in modifying resistance to oxidative stress.  We use acute exercise and forearm ischemia/reperfusion to challenge the redox balance and typically measure the responses over a time course using different markers of redox signaling. We have recently shown that cell signaling that contributes to the adaptive response to exercise is impaired in aging. Other recent or current projects in the lab include comparison of the redox response of high intensity interval cycling to cycling at a constant workload, gender differences in the response to forearm ischemia/reperfusion, and age-related differences in telomerase activity induced by acute exercise.

The long-term goal of my research is to identify intervention(s) that can restore the age-related impairment in redox cell signaling and to link these improvements to functional outcomes. I am particularly interested in whether the effects of a regular exercise program can be enhanced by phytonutrients known to activate redox signaling pathways.
