We develop musculoskeletal models and simulations to evaluate the effects of abnormal gait mechanics on muscle function and joint loading. Here are a few recent examples. 
An improved musculoskeletal model of the knee for resolving medial-lateral tibiofemoral contact forces:

The paper describing the model and validation can be found here.


Subject-specific modeling to evaluate the effects of pediatric obesity on medial knee joint loading

 
The creation of a sheep hind limb musculoskeletal model from experimental measurements:

The paper describing the model and validation can be found here.
