Research & Clinical Interests
His training in both basic science and applied research methods allows him to address clinically relevant questions with translation approaches thereby bridging the gap between bench and bedside. His initial work has contributed to the understanding of tissue adaptations in throwing athletes and how they relate to overuse shoulder injuries using novel diagnostic ultrasound methods. In addition, his basic science work studying the tissue and biologic adaptations to chronic rotator cuff tears and the effects of type II diabetes has also helped progress the current field. His current research agenda is two-fold and includes integration of translational research to investigate 1) the structural and biologic mechanisms governing soft tissue adaptation caused by the repetitive stress of throwing and the association with throwing biomechanics and 2) the structural, neuromuscular, and biologic adaptations occurring due to chronic rotator cuff tears and repairs.
