Research Interests

The long-term goal of my research is to contribute to the development of effective treatments for tendon problems. Tendon complaints are one of the most common musculoskeletal disorders. This places a large burden on the United States healthcare system. Painful tendinopathies reduce the quality of life of afflicted individuals and limit their ability to complete activities of daily living. Little in vivo data exist to aid in the treatment or prevention of painful tendinopathies. I am interested in filling these knowledge gaps. Additionally, I wish to better understand the mechanisms regulating tendon adaptations to exercise, particularly in the elderly. My laboratory uses both human and rodent models to address our research goals.
