Our laboratory is focused on the study of soft tissue response to injury, stress deprivation and mechanical loading in a variety of tissues including the anterior cruciate ligament and shoulder capsule.

Animal modeling and cell culture, and molecular techniques are used to study cellular response to physical and chemical alteration in the environment with a specific focus on mechanotransduction pathways involved in these responses.
