  • Neuroplasticity and Sensorimotor Learning


Every aspect of our lives depends on our ability to move. The overarching goal of my research program is to understand how the nervous and muscular systems work together to maintain posture and generate movement. My research falls under two major themes. The neuroplasticity and adaptation research line tests how reinforcement feedback can subserve our ability to acquire new motor skills. The neuromechanics research line examines how the nervous system controls the complex physics of our bodies while striking a balance between efficiency and stability. To address these questions, I use a complementary blend of human experiments, theoretical work and computational modelling from the sensorimotor and biomechanics research fields. The long-term goal is to inform and develop rehabilitation paradigms to improve the quality of life for those suffering from neurological disease, such as Parkinson’s or Stroke.
