My name is Jack Chang Liu. I am a Ph.D. student in the Aerospace and Mechanical Engineering Department at the University of Notre Dame. Prior to this, I earned my master’s degree and worked as a Research Assistant in the Department of Mechanical Engineering at the University of Michigan – Ann Arbor.

My research interests span 3 major areas: Legged Locomotion, Biomedical Devices, and Mechanical Design.

On the one hand, I am interested in exploring mechanical designs to enable legged systems with new dynamic capabilities that will yield the optimal and desirable locomotion behaviors, thereby achieving the energetic efficiency, agility, stability, and robustness in legged robots/machines that reach and even exceed those of legged animals in nature.

On the other hand, I take interest in exploring the efficiency and efficacy of biomedical devices and techniques, and seek to provide novel mechanical designs for prosthetics, orthotics, and active exoskeletons that help restoring the locomotion skills of the disabled and can be used as training and rehabilitation devices for the injured.
