My research examines the regulation of skeletal muscle energy provision. I am particularly interested in the potential for exercise and/or nutrition to induce metabolic adaptations at the molecular and cellular levels in humans.

In addition to basic, mechanistic studies, I also conduct applied research that examines the impact of exercise training and dietary manipulation on sport performance. Recent work in my laboratory has focused on two main areas:

  1. Metabolic adaptations to low-volume, high-intensity interval training, with an emphasis on the regulation of oxidative energy provision.
  2. The potential for alterations in nutrient availability to impact the acute or chronic adaptations to exercise training.

Working within the PACE facilities, we plan to conduct larger-scale, randomized controlled trials in order to comprehensively examine the physiological and health-related benefits of low-volume HIT versus traditional high-volume endurance training. We are interested in the potential for high-intensity interval training (HIT) to improve health-related indices in various populations including those at risk for chronic diseases. Preliminary work from small proof-of-principle studies suggests that HIT is a time-efficient strategy to improve insulin sensitivity and reduce blood sugar levels in people at risk for, or afflicted by, type 2 diabetes.
