Description of Research
My research interests are the effects of diet, exercise, and obesity on substrate metabolism and energy expenditure. Currently, we are performing studies on the effects of different intensities of exercise and manipulations in dietary fat on fat oxidation. These studies are performed using whole-room indirect calorimetry. We are also currently performing an exercise intervention aimed at determining the effects of exercise on the different components of energy expenditure, particularly non-resting energy expenditure. In these studies, a variety of approaches are used to assess energy expenditure including doubly labeled water, indirect calorimetry, and accelerometry.

Benefit of CNRU
The major benefit of the CNRU for me has been the enhanced interaction and collaboration with other CNRU investigators. Additionally, the CNRU allows me to interact with junior investigators through the pilot project program and through the core laboratories. The core laboratories of the CNRU are critical to my research success. These laboratories provide services in a cost-effective manner than I could not develop in my own laboratory.
