Human Performance Lab
I am interested in developing assistive devices, both to augment human performance in healthy individuals, as well as to train or compensate for deficits in impaired individuals. My thesis focuses on a new type of control for ankle-foot prostheses in which transtibial amputees are given autonomy and feedback from their robotic prosthetic ankle.
