My research goal is to understand how our motor ability is constrained by the specific way the brain uses to represent information of the external/internal environment, and how and to what degree such representation can change over the course of one’s experience. To achieve this goal I use both behavioral analysis and functional magnetic resonance imaging (fMRI) techniques.

My past studies mainly focused on the human motor system studying, for instance, how laterality in the arm movement representation in the brain leads to laterality in learning ability when people coordinate two arms, or how sequence of motor action is represented in different areas of the brain. In CiNet I will extend my research area to more “input side”, such as visual system, for better understanding about how the two systems interact to create our behavior.
