Clinical Assistant Professor

Janus obtained his medical degree at the University of Hong Kong in 2015. Upon completing his internship at Queen Mary Hospital Department of Orthopaedics and Traumatology, he served as resident to Orthopaedics & Traumatology, Accident & Emergency, Surgery, and Neurosurgery departments as part of his training, and completed his basic surgical training in 2018. He subsequently joined the University of Hong Kong as clinical assistant professor in 2019, and completed his higher orthopaedic training in 2022, having passed the Joint Specialty Fellowship Examination by the Hong Kong College of Orthopaedic Surgeons and Royal College of Surgeons of Edinburgh.

Janus has presented in multiple international conferences and has received recognition for his work, from the application of artificial intelligence in hip fracture prediction to genomic analysis of patients with atypical femur fractures.

Janus is a competitive swimmer and medallist having represented the Hong Kong Orthopaedic Association. His interests also include Latin which he studied during his time at Harvard University, and aviation having received pilot training in Australia.
