Research Assistant Professors



Research Assistant Professor



Dr Zhang received the Bachelor of Science degree in Occupational Therapy from Sichuan University and obtained his postgraduate qualifications Master of Science degree in Neurological Sciences from The Chinese University of Hong Kong and PhD in Rehabilitation Sciences from The Hong Kong Polytechnic University. Before he was appointed a Research Assistant Professor, he worked as a postdoctoral fellow in the Assistive Technology Laboratory at the department.

Dr Zhang’s research interests are the utility of transcranial magnetic stimulation along with multimodal neurophysiological and neuroimaging techniques to reveal the recovery mechanism following various neurological and psychiatric conditions, and to optimize rehabilitation outcomes. Dr Zhang has years of research experience in transcranial magnetic stimulation, electroencephalography, as well as poststroke upper extremity management. He is also enthusiastic about the experimental application of innovative technology, such as closed-loop brain-computer interfaces, in translational rehabilitation research.

Dr Zhang's representative works include the utility of metaplasticity-elicited priming theta burst stimulation and novel neurophysiological biomarkers, including transcranial magnetic stimulation-evoked potentials and mirror visual feedback-induced rhythmic desynchronization, in poststroke rehabilitation. Dr Zhang is actively looking for research collaborations in the field of neuromodulation and neurorehabilitation.
