David was born in England to an Australian mother and a Scottish father. He was raised in Scotland and attended high school in Edinburgh before undertaking his degree in Logic and Scientific Method with Mathematics. His initial aim was to become a systems analyst, but some time spent teaching convinced him that this might be where he could best indulge his passion for mathematics and computing. Although Secondary trained, he soon became convinced of the need to provide a strong mathematical foundation for younger students and is now the co-ordinator of Years 5 and 6 at Churchie in Brisbane. David has a keen interest in how students develop problem-solving techniques and has written a book on this subject, which has become one of AMT’s best-sellers. He joined the AIC/CAT committee shortly after its inception and in 2008, took over from David Clark as Treasurer of AIOC and member of The Finance Committee.
