Academic Background

BSc, MSc (Guelph), PhD (Toronto)

Biography

The primary goal of my research is to gain a better understanding of the control of human movement. I am interested in the control of whole-body mechanics via sensory information from the environment (visual, proprioceptive, mechanoreceptive and vestibular). Additionally, I am interested in the effects of injury- or age-related damage/deformity and footwear/orthotic therapies upon the role of the foot in postural control, gait and sports. I hope to translate the outcomes of this research into interventions for reducing falls in the elderly and improving shoes/orthotics for everyday activities and sport.
