I trained as a paediatrician in Singapore and in paediatric endocrinology at the Royal Children’s Hospital in Melbourne, started the paediatric endocrinology service in KK Children’s Hospital in 1997 , and also helped to start adolescent medicine services in KK Childrens Hospital in 2007.

I have travelled to and taught on diabetes and endocrine topics all over the world both in developed and developing countries, on every continent except Antarctica . I have been looking after children and young people with diabetes of all types since 1992, been a somatropin prescriber since 1993-4, and an pump prescriber since 1998-99. I have spent much of my career in public hospital practice but also more than a decade in various international NGOs, professional organisations, and a few years in parliament, and in the last few years, teaching healthcare providers in Asia and Africa.
