Clinical Assistant Professor Chua Yang Chong won a national scholarship to read medicine at the University of Glasgow, UK. On graduation, he completed his housemanship and basic surgical training in Glasgow. He gained further experience in general and trauma surgery in St Bartholomew’s and the Royal London Hospitals. During this period, he was appointed as a surgical research fellow and embarked on a research project leading to a doctorate in surgery. He was awarded the Rosetree’s Research Fellowship and his projects eventually attracted full funding from the Medical Research Council of United Kingdom. He presented orally in the American Gastroenterological Association, British Society of Gastroenterology as well as Society of Academic and Research Surgery, UK. He was awarded the Young Investigator award and was the invited oral speaker to the World Congress of Esophageal Diseases (OESO) in 2008 and 2010 respectively. He obtained his Ph.D from University of London in 2011.

Dr Chua came to Singapore and was appointed as an AST registrar in cardiothoracic surgery in NUH in 2011. He exited from the programme with the FRCS C-Th (Edinburgh) in 2015. Upon entering the specialist register, he joined the National Cancer Centre Singapore as a thoracic surgeon (Associate Consultant). In 2018, he went to do his fellowship in thoracic surgery in Toronto, funded by Singapore’s ministry of health. While in Toronto, he was awarded full funding by Toronto General Hospital for a second fellowship in lung transplant surgery. Toronto performed the first successful human lung transplant in the world in 1983 and is currently the largest lung transplant centre in the world. He returned to Singapore and joined the National Heart Centre Singapore as a Consultant, and Thoracic and Lung Transplant Surgeon in November 2020. He is also the Director of Lung Transplant Programme at NHCS.
