- The Neuromechanics Lab investigates the effects of instability and uncertainty on human control of movement and posture. Experiments in the lab use a combination of approaches involving virtual reality, robotic interfaces, kinetic and kinematic analyses. Coupled with computational models, these investigations will provide greater insight into the interplay between the biomechanical and sensorimotor processes underlying human movement control and decision-making.
