Dr Reuben Wong is a Senior Consultant in the Division of Gastroenterology and Hepatology, National University Hospital (NUH), and an Associate Professor at the Yong Loo Lin School of Medicine, National University of Singapore (NUS).

He obtained his MBBS from NUS, and attained his MRCP (UK) in 2004. In 2008, Dr Wong became a Fellow of the Academy of Medicine, Singapore. He pursued his sub-specialty training at the University of North Carolina (UNC) Center for Functional Gastrointestinal Diseases under the mentorship of Professors Douglas Drossman and William Whitehead. Dr Wong remains an Adjunct Assistant Professor of Medicine at UNC, in recognition of grants secured and continuing collaborations.

As a sub-specialist in Functional Gastrointestinal and Motility Disorders, Dr Wong helms the Functional Gastroenterology Clinic and pioneered the first Gastroenterology-Psychology multi-disciplinary service locally. Following his training at UNC, Dr Wong, who is also Clinical Director of the Gastrointestinal Motility Laboratory, introduced the first High Resolution Manometry in Singapore. This laboratory has since established itself as a referral centre and regional training hub.

Dr Wong has research interests and publications over a wide range of subjects, but his forte remains in the realm of gastrointestinal motility, neuro-gastroenterology and Irritable Bowel Syndrome (IBS), which he actively pursues. Dr Wong also has a special interest and does research in the field of colorectal cancer screening, health systems improvement and physician accessibility. In recognition of his achievements, he has received several accolades, including three Young Investigator Awards and the National Leadership in Academic Medicine Award.

Dr Wong is also actively involved in undergraduate and postgraduate medical education through both teaching and education-based research, and he is the Director for Undergraduate Education in the Department of Gastroenterology. His passion for public outreach sees him serving as the President of the IBS Support Group of Singapore. Dr Wong is also a member of the National Colorectal Cancer screening committee. On the volunteer front, he also serves on the committee for the St Andrew's Home for the Aged and as Vice-President of the St Andrew's Cathedral Servers' Guild.
