Justin Chee is a Doctoral candidate at the University of Toronto, completing his studies at the Rehabilitation Sciences Institute and Institute of Biomaterials & Biomedical Engineering. He completed his Master of Science in 2011 at the University of Toronto in fields of Rehabilitation Science and Neuroscience. In his Master’s thesis, Justin developed a novel algorithm with which to quantify the foot placement patterns of rollator users using camera-based computer vision technology, such that gait parameters can be assessed objectively outside of a laboratory environment.

Justin is a recipient of the Multiple Sclerosis Society of Canada Doctoral Studentship Award for three consecutive years (2013-2016) as well as the NSERC-CREATE Collaborative Academic Rehabilitation Engineering Scholarship for the two preceding years (2011-2013). In his Doctoral dissertation, Justin explores how the mobility of individuals with multiple sclerosis can be enhanced by augmenting assistive mobility devices with biofeedback gait training capabilities. He is developing an instrumented rollator that aims to improve the everyday lives of individuals with multiple sclerosis (MS) by: 1) automatically-detecting changes in their walking patterns and brain function; 2) providing feedback to users about their stability in order to stimulate mobility improvements; and 3) improving how these individuals integrate into their communities by facilitating better communication with local health services. The expected outcome of this work is a new and improved mobility aid that can be utilized by members of the MS community to help them enhance their safe mobility and prolong their independence.
