Biography

Prof. Jack Jiaqi Zhang received his BSc in Occupational Therapy from Sichuan University (2016) and his PhD in Rehabilitation Sciences from PolyU (2022). He served as a Research Assistant Professor in the Department of Rehabilitation Sciences from 2023 to 2025. He was also funded as a visiting scholar for a laboratory attachment at RWTH Aachen University, Germany. His research primarily focuses on poststroke neurophysiology and the use of neurotechnology in neurorehabilitation, including non-invasive brain stimulation, closed-loop brain-computer interfaces neurofeedback, digital visual feedback, and assistive robotics. Prof. Zhang has published over 70 articles in reputable peer-reviewed journals, such as Stroke, Brain Stimulation, Journal of NeuroEngineering and Rehabilitation, Addiction, Journal of Neurology, etc. His research projects as PI have received competitive funding support from the National Natural Science Foundation of China, the Health Bureau of the Hong Kong SAR, and the RGC General Research Fund and the Germany/Hong Kong Joint Research Scheme.

Prof. Zhang's research programme focuses on three key areas in rehabilitation sciences:
(1) The role of interhemispheric competition in motor recovery after brain injury
(2) Optimisation of the spatial and temporal precision of motor cortex neuromodulation
(3) Clinical investigations of the effectiveness of innovative neuromodulation protocols for neurorehabilitation

Prof. Zhang is actively looking for research collaborations in the field of rehabilitation technology and neuroscience.
