Our research in computational biomechanics focuses on the use of the finite element method to examine the mechanics of soft and hard tissues. We have developed techniques to build subject-specific finite element models of soft and hard tissues directly from medical image data such as CT, MRI, OCT or microscopy images.
We have also developed constitutitve models and finite element implementations that capture the nonlinear, anisotropic and viscoelastic properties of materials such as ligament, tendon, cartilage and meniscus. Our last focus has been on capturing boundary conditions in numerical simulations that are unique to biomechanics such as residual/initial stress and position-dependent anisotropy. The techniques have been applied to the study of knee mechanics, shoulder ligament mechanics, cartilage defects, and the hip.
