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)
