• BSc, Human Kinetics, University of Guelph (2016)

Previous Research


• Developed analytical model to resolve the dynamic margin of stability within a non-inertial reference frame (known support-surface accelerations); this measure is often used as a quantitative outcome in human balance experiments.
• Approximated the feasible stability region (centre of mass position-velocity region) for a torque-driven model of frontal plane counterbalance postural strategies via predictive simulations.
• Evaluated fidelity of simplified anthropometric model variants for estimation of whole-body centre of mass kinematics during balance recovery. 


• Investigated the effect of repeated exposure to support-surface perturbations mimicking controlled slipping during walking on the kinematics of balance recovery.
