Research in the Musculoskeletal Research Laboratories has historically focused on the injury, healing and repair of musculoskeletal soft tissues, in particular the ligaments of the knee. Our research focus has expanded considerably over the past 5 years to include hard tissue as well as cardiovascular tissues including the heart, coronary arteries and smaller vessels involved in angiogenesis. A central theme of our approach to research is the use of multidisciplinary techniques. A primary strength of the MRL continues to be the combination of both experimental and computational techniques, especially in the area of biomechanics, to address research questions that would be impossible to investigate using approaches in a single technical discipline.
