Dr. Xin Song received his bachelor's and master's degrees from Sichuan University in Prof. Changsheng Zhao's group. He then obtained his Ph.D. at Imperial College London under the supervision of Prof. Molly Stevens DBE FRS FREng. Before joining CityU, he was a Research Assistant Professor in the Department of Mechanical and Automation Engineering at The Chinese University of Hong Kong, working with Prof. Li Zhang. Since 2025, he has been an Assistant Professor in the Department of Biomedical Engineering at City University of Hong Kong. Dr. Song's research focuses on the development of advanced intelligent materials and systems for therapeutic, purification, and diagnostic applications in blood environments, including blood purification devices, micro/nano robotic systems, and blood-contacting biomaterials.
