Dr. Chen received his M.D. in medicine from the Capital Medical University, Beijing, China, in 2011. He completed his doctoral training in the Department of Orthopaedic at Beijing Chao-Yang Hospital (in 2016, China). From 2013 to 2016, Dr. Chen worked at the Beijing Chao-Yang Hospital as a Spine Surgeon. In 2018, he joined Spine Labs of UNSW for doctoral training. Dr Chen has been awarded many international grants, including The International Society for the Study of the Lumbar Spine (ISSLS) traveling fellowship award (clinical fellow at Spine Service, UNSW, Australia), AOSpine clinical research award, NASS traveling fellowship award (fellow at Keck Hospital, USC, USA), International ISSLS Young Investigator Travel Grant, etc. Dr Chen’s previous work focused on the studies on big data and databases, biomechanical and biological changes, and clinical related research in degenerative spine diseases.

Dr. Xiaolong Chen is an early-stage investigator in translational research of degenerative spine diseases. Dr Chen focuses on the efficacy and complications following different surgeries for degenerative spine diseases via big data and database (network meta-analysis, meta-analysis, and systematic review), biomechanical, radiological, and clinical studies.

Dr. Chen’s PhD thesis entitled “Studies in Failures of Discectomies” presents series of studies (e.g., big data and database, biomechanical, biological, radiological, and clinical studies) investigating a hierarchy of complication rates following different discectomy techniques, and then explores factors like surgical technique variations, altered tissue molecular markers, and disc height measurements in the context of discectomy. The findings revealed that a plethora of techniques used for measuring disc height index were never subjected to the proper evaluation.

Based on his PhD study, Dr. Chen and his team developed a novel nucleus replacement device (https://www.kunovus.com) for treating the patients with lumbar disc herniation. His ability to evaluate an elastomeric disc spacer biomechanically and to conduct an early clinical trial was curtailed due to the pandemic during the PhD period. However, he is pursuing that as his post-doctoral work at Kunovus Technologies for the biomechanical and biocompatibility testing and clinical trial of the novel nucleus device.

Dr. Chen collaborates some international research institutions for many projects.
