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.
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.
