Dr Chan graduated from the University of New South Wales in 1986 with a Bachelor in Medicine and Surgery. After gaining experience in general medicine, surgery, emergency medicine and paediatrics, he developed an interest in obstetrics and gynaecology. He received the Gold Medal for the MRANZCOG examination in 1990 and was admitted to the Westmead Hospital Integrated Training Program, becoming the first fellow in gynaecological oncology at the hospital.
In 1996 Dr Chan undertook his fellowship at King Edward Memorial Hospital, Perth, where he developed a keen interest in defining the role of laparoscopic surgery in gynaecological oncology. In 1997 he had the opportunity to work alongside leading UK specialists at St Bartholomew's, Royal Marsden and Royal London Hospitals. He gained further expertise in gynaecological surgery after attending a master class with French surgeons Dr Queleu and Dr Dargent, and UK surgeon Professor John Monaghan. Dr Chan is currently Director of Gynaecological Oncology at Liverpool Hospital, treating women with gynaecological malignancies. He also operates out of Macquarie University Hospital.
