Professor Enders Ng obtained his medical degree from the Chinese University of Hong Kong in 1989.  He embarked on both basic and clinical research shortly after finishing his surgical training in the mid-1990s. He received the higher degree of Doctor of Medicine (CUHK) in 1999 for his work on investigating the relationship between Helicobacter pylori and peptic ulcer diseases. His other research foci include interventional endoscopy and surgical oncology for oesophagogastric malignancies. Over the years, he was awarded by different authorities and societies for research achievement, including Young Scientist Research Prize in the 4th United European Gastroenterology Meeting (1994) and Young Scientist Award in the 11th International Workshop on Gastroduodenal Pathology and Helicobacter pylori in Hungary (1998).  His work on peptic ulcer complications has also led him to the winning of Second-Class Award of the 2007 State Scientific and Technological Progress Award of China.  Up to now, he has published over 200 articles in various international peer-reviewed journals and more than 10 book chapters in Surgery and Endoscopy.

Professor Ng's interest of research has expanded to metabolic and bariatric surgery, as well as surgical nutrition in the last decade.  He was the Founding President of the Hong Kong Society of Upper Gastrointestinal Surgeons from 2006 to 2010. He is also the President of Hong Kong Society of Parenteral and Enteral Nutrition since 2007.  He has been repeatedly elected as Councillor of the College of Surgeons of Hong Kong since 2007, and was the Vice-President (Internal Affairs) from 2013 to 2019.  He is now the Associate Dean (Alumni Affairs) to the Faculty of Medicine, The Chinese University of Hong Kong. His current post is the Chief of Service in Surgery at Prince of Wales Hospital and also the Cluster Surgery Director of the New Territories East Cluster of the Hospital Authority.  He is a keen teacher and trainer. His passion and enthusiasm in medical education has led him to become the curriculum coordinator for the final year curriculum of the medical school since 2015.  His fondest hobbies are Chinese Calligraphy, hiking and Endurance Running.
