Research Interests

focuses on understanding the neural and biomechanical factors involved in the normal control of multi-joint movement and posture and how these factors are modified following neuromotor pathologies such as stroke and spinal cord injury. The goal of this research is to provide a scientific basis for understanding normal and pathological motor control that can be used to guide rehabilitative strategies and user interface development for restoring function to individuals with motor deficits. A combination of human and animal experimentation, system identification and computer simulations is being used to achieve this goal.
