Profile
Biography
I am a biomechanist with a particular interest in the neuromechanical control of movement. In order to understand how we move in complex environments I have previously used a comparative approach, studying both human and animal locomotion, but my focus recently has moved into human movements. I use complex environments as a way to address the underlying control principles, as it is within these complex tasks that performance limitations will be reached and trade-offs occur due to changing mechanical demands. Determining the underlying control of movement has the potential to inform on clinical practice, rehabilitation strategies, legged robotics and assistive technologies.
