CV



I am a postdoctoral fellow at the Mechanical Engineering Department of Stanford University. I work with Drs. Steve Collins and Chris Atkeson to develop control algorithms for exoskeletons that can improve human locomotion performance. As individual users adapt their behaviors differently and accordingly to external assistance, better facilitating this adaptation in a customized way will be a key for maximizing the effect of exoskeletons.

My overall goal is to better understand and model the motor control and biomechanics of human locomotion and to apply the obtained knowledge to rehabilitation engineering. I develop computational models and conduct human experiments to propose and evaluate control hypotheses. During my Ph.D. studies, at Carnegie Mellon University with Dr. Hartmut Geyer, I have focused on developing and evaluating neuromechanical control models to understand the circuitry-to-behavior layer of human locomotion. I envision my research to bring about simulation testbeds (which I call the digital locomotor clones) for training protocols and assistive devices as well as intelligent motion controllers for assistive and humanoid robots.

You can download my neuromechanical model here.
