Personal statement

My current research efforts include the study of :(1) the physics of human movement (i.e. biomechanics), including tasks from walking and running e.g. the effect of side slopes – such as with the indoor track – on rear foot motion and upper body posture/balance; the effect of fatigue on lower limb kinematics / in shoe loading dynamics / electromyography (EMG) recruitment changes during long distance running; measurement of fore-rear foot torsion during running) and the unique context of locomotion on ice i.e. skating in ice hockey (e.g. the relation of ice hockey performance and design issues related to the skate such as : in boot rear foot kinematics using goniometers; in boot pressure patterns during various skating tasks; measurement of muscle activation patterns using EMG during skating, and (2) the impact tolerances of the human body e.g. ice hockey helmet impact performance with aging and use; global dynamic pressure measures between helmet and head during impact; computer modeling of impact behavior of helmets; effect of foam densities and geometries on impact distribution; and impact distribution to soft tissues of the upper and lower limbs.
