Research Interests:  I am interested in the influence of age and physical activity on systemic and skeletal muscle inflammation.  I am particularly interested in the mechanisms that underlie the anti-inflammatory effects of exercise training and the connections between inflammation and risk factors for chronic diseases/conditions such as cardiovascular disease, type II diabetes, and sarcopenia.

Courses Taught: 

KNH 382 Exercise Testing and Prescription
