Stephen has written eleven books, which have been translated into 24 languages, including his series of "Odd" books which are filled with weird, wonderful, informative and entertaining facts about the human body and human behaviour.  His talent for making the clinical both clear and entertaining has contributed to the success of these books, in which he delves into such biological mysteries as to why we hiccup and explores brain phenomena such as déjà  vu.

He is a man of wide-ranging interests, with a research focus in the areas of anthropology and education, child development, parenting education and science education.  His internationally syndicated newspaper column appears in newspapers all around the world and he is a regular guest on television and radio programs in Australia, Canada, and the United States of America.
