Personal profile

Training Experience

My background is in electrical and biomedical engineering with specific training and experience in robotics, human biomechanics and movement and rehabilitation science. The broad focus of my research is to characterize the mechanisms underlying the loss of independent joint control of the arm, leg and trunk following brain injury due to stroke. I am interested in applying the knowledge of the mechanisms underlying the motor impairments gained from this research to devise and implement new approaches for delivering effective arm rehabilitation interventions to stroke survivors. The main approach that I am pursuing in my research is the development of portable robotic devices that can be used for therapeutic and diagnostic purposes to help stroke survivors regain movement of the arm.
