Biography in Brief:

Dr. Lum's area of study is the application of engineering tools to assist development of novel interventions for rehabilitation of movement following neurological injury. Following his doctoral studies, he served from 1994-2002 as Research Biomedical Engineer at the Rehabilitation Research & Development Center in the Dept. of Veterans Affairs Palo Alto Health Care System. There, he developed the MIME robotic system for rehabilitation of arm movement after stroke. In 2002, he and colleagues published the first controlled study that demonstrated the advantages of robotic arm therapy compared with dose matched conventional therapy.  He started as an Assistant Professor in Biomedical Engineering at Catholic University in 2005, and was promoted to Associate Professor in 2007. He currently directs the Center for Applied Biomechanics and Rehabilitation Research at MedStar National Rehabilitation Hospital, and is also a Research Health Scientist at the Washington DC Veterans Affairs Medical Center. He is currently developing robotic devices for hand function, studying motor learning and performance limitations in amputee populations, and continuing work in telerehabilitation technologies.
