 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.
