Research in the SFU Locomotion Lab focuses on understanding the fundamental principles that underlie the physiology of legged locomotion as well as the application of these principles to improve human health. We use a combination of mathematical modeling and empirical experimentation with the latter involving techniques from biomechanics, energetics and neurophysiology. At a fundamental level, a more complete understanding of legged locomotion provides insight into the behavior, ecology and evolution of animals. At a more applied level, understanding locomotion is useful in the design of legged robots or energy harvesting devices. A better understanding of the mechanics, energetics and neural control of human locomotion has many clinical applications.
