Profile

Dr Tan is a Consultant Surgeon with the Department of Hepatopancreatobiliary and Transplant Surgery.

He graduated from the National University of Singapore in 2008 and completed his General Surgery training at the Singapore General Hospital. During his training, he was awarded the National Medical Research Council Overseas Research Training Fellowship to study the effects of ischemia-reperfusion injury on hepatic oval cells with Dr Ari Cohen at the Ochsner Clinic, USA. He is a Fellow of the Royal College of Surgeons (Edinburgh), and holds a Master of Medicine (Surgery) from the National University of Singapore, and a Master of Public Health from the Bloomberg School of Public Health, Johns Hopkins University. Upon completing his specialist training he underwent further subspecialty training with an American Society of Transplant Surgeons (ASTS) accredited 2-year fellowship program in abdominal organ transplantation at the Mayo Clinic (Rochester), USA.

Dr Tan’s clinical practice is focused on abdominal organ transplantation and conditions involving the liver, pancreas, and biliary tract. He adopts a collaborative multi-disciplinary approach to deliver individualized care to each patient. His clinical efforts are directed primarily at improving outcomes after organ transplantation, and in the treatment of advanced cancer.

He is committed to an academic surgical practice, with active interests in tumour biology, immunology, and novel therapeutics in the treatment of cancer. He also has research interests in health policy and data analytics, which he believes can guide decision-making for clinicians to improve healthcare standards. He is engaged in medical education and the training of budding surgeons through the use of technology and adaptive learning methods.
