Dr. Chang has published more than 30 scientific articles in international Obgyn journals. He has written two hugely popular books on pregnancy for the public. The first, “Doctor I want to know is my pregnancy healthy?” was published in 2002 and has sold more than 5000 copies to date. His latest book, co-authored with Mrs. Wong Boh Boi, a ParentCraft Teacher, is entitled “Pregnancy and Childbirth” (published by Marshall Cavendish in 2008)

Scientific Lectures​

Dr. Chang is passionate about post-graduate teaching and has given lectures on high-risk pregnancies and obstetric ultrasound at numerous scientific congress and meetings throughout the world (in UK, USA, Canada, New Zealand, Taiwan, Hong Kong and Singapore). Dr. Chang also taught Obstetric Ultrasound at ultrasound courses that he organized, a Certificate Course in Obstetric Ultrasound jointly with Monash University, Australia (2003) and a Certificate Course in Obstetric Ultrasound jointly with the College of Obstetricians and Gynaecologists, Singapore (2006). He was also the co-chairman of the organising committee, International Society of Ultrasound in Obstetrics and Gynaecology Outreach Course/ College of O & G Singapore Congress in November 2008.

In 1995, Dr Chang was awarded the Benjamin Henry Sheares Gold Medal by the Obstetrics and Gynaecological Society of Singapore (OGSS) for his lecture on the “Ultrasound Diagnosis of Fetal Growth Restriction”. As President of the College of O & G, Singapore (2007 – 2009), Dr. Chang also represented the College at official functions and international medical congresses.
