Get to know more about us

Our team uses structural engineering analysis tools to determine the material properties of soft tissue and to predict its response to mechanical actions.

Until recently, all of our work has been on ocular biomechanics but now includes applications in the musculoskeletal system, pancreas and skin. We will be happy to look into other areas depending on external interest and funding.
