Dr Graham Shea graduated from the University of Hong Kong as a member of the first cohort of candidates recruited to the combined MBBS / PhD programme.  After completing his internship, he joined the Department of Orthopaedics and Traumatology as Clinical Assistant Professor and Resident under the Croucher Foundation Scheme for Young Clinical Academics.  He received his FRCSEd (O&T) in 2019 and has a post-fellowship clinical and research interest in spine surgery and regenerative medicine. 

Research Interests

  • Basic / clinical studies on the pathophysiology and treatment of cervical spondylotic myelopathy
  • Use of artificial intelligence for prognostication of spinal disorders
  • Ontogeny and application of bone marrow-derived neural progenitors towards cell therapy
  • Application of chondroitinase ABC to treat chronic wounds

Research Opportunities

Projects in the above areas are available for research postgraduate students and postdoctoral fellows who are highly motivated individuals. A background in molecular biology, biomaterials and drug delivery is preferred for ongoing basic science projects.  Enthusiastic and committed candidates are encouraged to contact me via email.
