Qi Wei, PhD


Qi Wei joined GMU in August 2012, after completing her postdoctoral training in Professor Matt Tresch's lab in the Department of Physiology at Northwestern University. She received her Ph.D. in Computer Science from Rutgers University and M.Sc. in Computer Science from The University of British Columbia, supervised by Professor Dinesh Pai. Dr. Wei's research interests include biomechanical modeling and simulation, eye movement, and medical image analysis.

Dr. Wei leads the Biomechanics lab. The research in our lab focuses on developing and applying computational models to study disorders of the oculomotor system and the musculoskeletal system. In collaboration with Prof. Siddhartha Sikdar, the lab examines the application of Droppler ultrasound to quantitatively measure extraocular muscle dynamics in vivo. The research is funded by the Jeffress Trust Award Program.

Together with Prof. Tresch and other researchers at Northwestern University, we study the biomechanics of the rat hind limb, which can help us to understand fundamental questions in the neural control of movement. The project is supported by a NIH R01 grant. Using a state of the art biomechanical model of the ocular motor plant, the lab examines the coordination of extraocular muscles as well as the biomechanics of strabismus. The MRI data was provided by our collaborator at UCLA.
