Biography

Dr. X. MA (Xin MA) is currently a Research Assistant Professor in the Department of Data and Systems Engineering, The University of Hong Kong (HKU), secured funding in the URC PDF/RAP Scheme (49^th round). Dr. Xin Ma was a Postdoctoral Fellow in the Department of Data and Systems Engineering at the University of Hong Kong from 2023 to 2025. Dr. Ma received his Ph.D. degree in Computer Application Technology from Fudan University. Dr. Ma’s research interests include the dynamics and control of human-robot systems, with applications in fall prevention and rehabilitation of muscle dysfunction, as well as the development of wearable assistive robots. He has published his research as the first author in top-tier journals, including IEEE Transactions on Fuzzy Systems (a top journal in control theory), International Journal of Mechanical Sciences (a top journal in mechanics), and IEEE Transactions on Neural Systems and Rehabilitation Engineering (a top journal in rehabilitation). Dr. Ma received the Best Student Award at IEEE ROBIO and serves as an ad-hoc reviewer for journals including IEEE-CAA J AUTOMATIC, IEEE TFS, ND, and AMS. He has contributed to several major research grants, including the NSFC (Key Project), the National Key R&D Program of China, and the Theme-based Research Scheme (TRS). Notably, his research outcomes have benefited over 1,000 older adults in Hong Kong.
