Dr Wai was born in Hong Kong and took the Ministry of Education scholarship to study in Singapore, and had decided to make Singapore his home since then. He obtained his Bachelor of Medicine and Bachelor of Surgery degree from the National University of Singapore in 1998. He obtained his membership of the Royal College of Physician (United Kingdom) and Master of Medicine (Internal Medicine) Singapore in 2001. He subsequently had his advanced specialist training in the Singapore General Hospital and completed it in 2006. From 2007 to 2008, he went to the Alfred Hospital and Baker Heart Research Institute in Melbourne, Australia for further training in management of lipid disorders. He ran the Lipid Clinic upon his return, treating many patients with hard-to-treat cholesterol problems. In 2010, he was made the Director of the Obesity and Metabolic Unit of his department, leading a team of doctors, dietitian, physiotherapist and psychologists to provide the medical and surgical treatment for obesity and cholesterol problems.

Dr Wai had given over 135 local and international lectures over the years, on topics on diabetes, cholesterol, obesity and thyroid. The audience ranged from the public, medical students, physiotherapists, dietitians, traditional Chinese physicians, ca-rdiologists, ophthalmologists and other internal medicine specialists. He was Adjunct Assistant Professor of the medical faculty of the National University of Medicine from October 2010 to Dec 2011.

Dr Wai was active in research and was principle investigator of studies in genetics of cholesterol, visceral fat, ca-rdiovascular risk factors and thyroid eye disease, with funding from the National Medical Research Council and Biomedical Research Council. He was also regularly invited by those research institutes as a reviewer of research grant application, as well as reviewer of research papers in local and international journals.

As interesting as leadership, teaching and research are, Dr Wai remains most passionate about patient care. He was awarded the Service with A Heart Award by the Singapore General Hospital 3 times, in recognition of the excellent service he had given to his patients. He speaks English, Mandarin, Cantonese and Bahasa Indonesia. He was regularly interviewed by the Media regarding topics on obesity, diabetes and cholesterol care (see Media section).
