Research Interests


Sensorimotor physiology, balance, whiplash


Researchers in the Sensorimotor Physiology Laboratory investigate human physiology from an integrative perspective. Specific research interests include i) physiological processes underlying human balance, ii) physiological responses evoked by whole-body (simulating whiplash motion) or localized perturbations and iii) neural control of the deep and superficial neck muscles. The work on whiplash injuries is performed in collaboration with MEA Forensic Engineers & Scientists in Richmond, BC. Some research projects are applied to injury prevention or patient populations to determine the neuromechanical effects of known injuries/pathologies on the sensorimotor system.

The Sensorimotor Physiology Laboratory is equipped with feedback-controlled motors, 3D motion, accelerometry and force systems as well as neural and physiological measurement and stimulation units. A large 6 DoF robot and virtual reality display are also available through collaborations with the Institute for Computing, Information and Cognitive Systems and Collaborative Advanced Robotics and Intelligent Systems on the UBC campus.
