Qi Wei leads the Biomechanics lab at the Volgenau School of Engineering at George Mason University. The lab’s research focuses on developing and applying computational models to study disorders of the oculomotor system and the musculoskeletal system. Using an advanced biomechanical model of the ocular motor plant, the lab examines the coordination of extra-ocular muscles as well as the biomechanics of strabismus. MRI data contributions were shared with Mason’s team from research collaborators at UCLA. Recently, the lab developed a dynamic model of an arm, which is used to understand the biomechanical factors in motor learning. In collaboration with Siddhartha Sikdar, the lab examines the application of Doppler ultrasound to quantitatively measure extra-ocular muscle dynamics in living subjects. The lab is also studying the biomechanics of the rat hind limb, which can help scientists to understand fundamental questions in the neural control of movement.
