The main focus of my research is adaption of musculoskeletal tissues to the mechanical environment, injury, aging, or disease. The musculoskeletal system has an innate ability to repair and optimize itself based on the mechanical demands placed on it. By studying this adaptation, we are able to uncover underlying mechanisms that contribute to diseases such as osteoporosis and osteoarthritis.
My laboratory primarily utilizes small animal models, and quantifies adaptation using advanced imaging techniques, histology, and mechanical testing. I currently have three primary areas of research: investigation of mechanisms of post-traumatic osteoarthritis, investigation of systemic bone loss following a bone fracture or other injuries, and investigation of the role of sensory nerves in bone metabolism and adaptation.
