--> Research Interests

Generally, I am interested in the mechanics, energetics, and control of terrestrial locomotion.

For my doctoral dissertation studies I used powered exoskeletons as a tool to understand the contribution of ankle joint mechanical power to the metabolic cost of walking.

The overall goal of my laboratory is to use biological principles to develop better lower-limb robotic devices to assist both healthy and impaired human locomotion (e.g., post-stroke).

My current research focus is on the mechanics and control of compliant muscle-tendon units (e.g., ankle plantarflexors). I use simple mathematical models to explore how elastic mechanisms can be exploited to allow for economical force production and optimal mechanical energy transfer during cyclic movements, particularly in the context of mechanical assistance from wearable robots (e.g., exoskeletons). Model predictions are then tested experimentally in (1) human Achilles' tendon-triceps surae in vivo during walking, running and hopping (using ultrasound) and (2) bullfrog plantaris muscle-tendon in vitro during simulated locomotion (using sonomicrometry and real-time emulation of dynamical systems through 'smart' ergometer interfaces) .
