The integrative biology of exercise

Research Description

Dr. Rossiter's research mission is to improve the lives of patients in whom exercise intolerance is a major symptom. For this he uses a range of in situ, in vivo, and computational methods to study physiological responses to exercise with special reference to chronic pulmonary diseases and pulmonary rehabilitation. His lab conducts respiratory research and clinical trials focusing on the following areas:

1) Control of oxidative phosphorylation, mitochondrial function and their contribution to metabolic health and biological aging.
2) The mechanisms of exercise intolerance, muscle fatigue and symptom limitation in health and chronic disease.
