Michelle Johnson, PhD is an Associate Professor in the Department of PM&R at the MCW and the Department of Biomedical Engineering at Marquette University. She completed a post-doctoral fellowship under the direction of Professor Paolo Dario of the Department of Biomedical Engineering, Scuola Superiore of SantAnna and Director of the Polo SantAnna Valdera Research Center and Professor Eugenio Guglielmelli of the Department of Biomedical Engineering and Director of the ARTS Lab and the RTR Center. This work was focused on design and development of low cost, modular, assistive technology, i.e., robotic, mechatronic, domotic/telematic technologies for elderly and severely disabled persons with upper limb disabilities. Her dissertation work was completed under Professor Larry Leifer, director of the Center for Design Research at Stanford University, and Machiel Van der Loos, Ph.D. of the Palo Alto Veterans Affairs Health Care Center Rehabilitation Research and Development Center. This work was centered on the design of a robot-assisted stroke rehabilitation therapy device, which incorporated a force-feedback control strategy inspired by a motivational-based clinical rehabilitation strategy.
