My main interest is in prevention of
age-related disease and the promotion of successful aging. The research in my
laboratory focuses on the role of exercise (and nutrition) in modifying stress
resilience, measured by using physiological and/or psychosocial stressors to
challenge the system and assessing the physiological response to the challenge.
Increased stress resilience translates to greater protection against diseases
and chronic conditions associated with aging and sedentary lifestyle. My recent
studies focus primarily on oxidative stress and modification of the capacity to
resist oxidative damage. The long-term goal of my research is to determine the
role of oxidative stress in the aging process; in particular whether a regular
exercise program results in systemic changes in the capacity to resist
oxidative stress in previously sedentary individuals. The mission of my
laboratory is to enhance the understanding of the interaction between exercise,
antioxidants, and biomarkers of aging and age-related diseases, using a
clinical approach. Successful interventions can be further developed as
preventive medicine and have the potential to improve the health and quality of
life of the aging population.
