The focus of our research is the influence of physical activity and exercise on cardiorespiratory fitness and long-term health outcomes in various populations.

This research involves collaborations with investigators both within and outside of Washington University School of Medicine, as well as with community partners in St. Louis. These collaborative activities encompass investigations of novel cardiac rehabilitation programs, long-term calorie restriction among healthy adults as a strategy to modulate aging, longitudinal assessments of aerobic capacity among adults with heart failure, and novel nutrition-based therapies to improve aerobic capacity in patients with heart failure
