Dr. Cheng-Di Chiu is a clinical scientist and neurosurgeon at China Medical University and University Hospital. His work mainly focuses on the biological mechanism that participates in the formation/progression of hemorrhagic stroke by studying the key cell types and immunological factors which regulate the integrity of blood–brain barrier in early period of injury. He also investigates surgical and interventional approaches used to mitigate symptoms of disc degenerative disease. As a member of CMUH Spine Center, he now designs and performs MSC-based therapy for sub-acute stage spinal cord injury, which was one of the leading protocols accepted by the Taiwanese government and has been launched in CMUH since May 2021.
