Clinical Assistant Professor
Honorary Resident Specialist
Dr Jason Pui Yin Cheung joined the Department of Orthopaedics and Traumatology as a Clinical Assistant Professor in November 2012. After obtaining his MBBS degree from The University of Hong Kong in 2007, Dr Cheung received his training in Orthopaedics at Queen Mary Hospital. He completed his membership examination in 2009 and obtained his Masters of Medical Sciences degree from The University of Hong Kong in 2012. He completed his specialist training in 2014. He obtained his Master of Surgery in 2017 and Postgraduate Diploma in Molecular and Diagnostic Pathology in 2018. His main research interests are paediatric growth and spinal deformity, developmental lumbar spinal stenosis, management of cervical myelopathy and orthopaedic infections.
