He is a dual specialist in Infectious Disease and Gastroenterology & Hepatology. He obtained his medical degree from the University of Bristol Medical School, England in 1996. After working in the University of Cambridge Medical School and Charing Cross Hospital, the Imperial College Medical School, London, he returned to Hong Kong in 1999 and joined the Department of Medicine, Queen Mary Hospital. After obtaining his MRCP, he underwent subspecialty training in Infectious Diseases, followed by Gastroenterology and Hepatology. He was a Visiting Fellow at the Division of Geographical Medicine and Infectious Diseases, Tufts-New England Medical Center, Boston, USA.

He is currently the Fellow of Royal Colleges of Physicians of London and Edinburgh.
He has published more than 150 international peer reviewed original articles, including research articles in the Lancet, the Lancet Infectious Diseases and the Clinical Infectious Diseases. He and his team have pioneered the use of topical imiquimod before intradermal influenza vaccination, which results in protection against heterologous non-vaccine and antigenically drifted viruses (Lancet Infectious Diseases). His team was also the first to prove convalescent plasma and H-IVIG reduced mortality in patients with severe influenza infection in prospective clinical trials (Clinical Infectious Diseases and Chest).
His research interest includes vaccine, innovative treatment of severe influenza and prevention of pneumococcal infection, treatment of resistant Helicobacter pylori infection, novel endoscopy techniques, and hepatitis B related hepatocellular carcinoma. He is ranked as University of Hong Kong top 1% scientists in 2013, with an H-index of 32. He is the Board & Founding Member of the World Association for Infectious Diseases and Immunological Disorders (WAidid), member of 8 international advisory boards for vaccine and infectious diseases. He is Section Editor for the BMC Infectious Diseases and editorial board member of the Journal of Gastroenterology and Hepatology, Journal of Interventional Gastroenterology and the Scientific World Journal. He is a regular reviewer for journals including the Lancet, Annals of Internal Medicine, Vaccine, Clinical Vaccine and Immunology, Endocrine, Clinical Obesity, Gastrointestinal Endoscopy, Helicobacter, Journal of Gastroenterology and Hepatology, Digestion and the Hong Kong Journal of Medicine.
