About Me

I left Malaysia for boarding school (The Leys School in Cambridge) in the United Kingdom in January 1977 after completing Form 5 in Bukit Bintang Boys' Secondary School in Petaling Jaya in December 1976. Since the academic year begins in September in the UK I had missed a whole term of school. Nevertheless, my hard work was rewarded with top grades in the Advanced and Scholarship Level examinations in the summer of 1978 and I was awarded the Josiah Stamp Prize for Science. I started medical school in September 1978 and graduated from the United Medical Schools of Guys and St Thomas's Hospitals, University of London, in July 1983, having won four prizes in medical school, including a Confined War Memorial Clinical Scholarship. I joined St Mary's Hospital Medical School in London, which later became part of the Imperial College School of Medicine, in January 1986 as a Lecturer / Honorary Senior Registrar. After completing my training at St Mary's Hospital in clinical biochemistry and metabolic medicine, and successfully obtaining my MSc, MD and membership on the first attempt, I moved up to Newcastle upon Type to commence my appointment as Consultant/Head of Department of Clinical Biochemistry at Freeman Hospital and Senior Lecturer in the Department of Clinical Biochemistry and Metabolic Medicine at the Medical School, University of Newcastle upon Tyne on 1st October 1990. After having been offered a position within the newly established medical faculty at Universiti Putra Malaysia, I returned to Malaysia to take up the post of Professor of Clinical Biochemistry and Metabolic Medicine and Deputy Dean on 2nd January 1997. I then joined the International Medical University as Professor of Medicine and Dean of the Postgraduate Medical School in August 2001. I started full time private practice as a Consultant  Endocrinologist at Gleneagles Kuala Lumpur in March 2004, having commenced part-time private practice at the same hospital in 2001.
