Dear Patients, Visitors & Friends:

This website is intended to provide you with some background information about myself and my clinical subspecialty. If your are here to seek medical consult, I hope the information may be of help to ascertain if your needs would be appropriately met.



After graduating from the Faculty of Medicine, National University of Singapore in 1987, I pursued training in Internal Medicine leading to the awards of Master of Medicine in Internal Medicine from NUS and Postgraduate Diploma in Internal Medicine from the Royal Colleges of Physicians, United Kingdom, in 1992. I further pursued subspecialty training in Endocrinology which I completed in 1997 with Specialist Certification in Endocrinology by the Joint Committee on Specialist Training & Specialist Accreditation Board, Ministry of Health, Singapore.

I had the privilege to enrich my subspecialty training in Endocrinology with Overseas Clinical Fellowship Awards which allowed me the opportunity to work and train under some of the world-renowned leaders in diabetes, lipids, thyroid and neuroendocrine disorders from two outstanding academic centres in North America:

  • Division of Endocrinology & Metabolism, Dalhousie University, Halifax,
    Canada (1995-6);

  • Metabolic Research Unit, University of California at San Francisco,
    California, USA (1996-7).

During my professional career, I have been admitted as a Fellow to the American College of Physicians, American College of Endocrinology, Academy of Medicine, Singapore, and Royal College of Physicians of Edinburgh, United Kingdom, respectively.


Prior to the commencement of my private practice, I was a Senior Consultant in the Endocrine Unit, Department of General Medicine, Tan Tock Seng Hospital. I also held concurrent appointments as Visiting Consultant to the Reproductive Medicine Unit of KK Women’s & Children’s Hospital and the Thyroid Clinic at the National Cancer Centre, respectively. I also taught part-time as Clinical Lecturer, Faculty of Medicine, National University of Singapore; and as Visiting Lecturer, School of Health Sciences, Nanyang Polytechnic.


I have an active interest in clinical research and I have presented (in international scientific meetings) and published my work quite extensively. Most of my publications in scientific journals/ book chapters are available upon request (refer to Publications).

My interest and clinical practice spans the whole spectrum of endocrine & metabolic disorders. Nevertheless, I have an active interest in the thyroid, including thyroid cancer and ultrasound-guided procedures for thyroid nodule (refer to Clinical Services).

I was the Editor of Medical Digest (1999-2002), a medical periodical that is circulated to all medical practitioners in Singapore.
