Currently working as as Associate Professor at The University of Sydney, Western Avenue, Sydney, New South Wales 2006. He is a paediatrician specialising in treating children with attention deficit hyperactivity disorder (ADHD). Studied medicine at Girton College Cambridge and Guy’s Hospital London, qualifying in 1982. I trained in paediatrics in Stoke-on-Trent and Birmingham UK before migrating to Australia. I completed my advanced training in Melbourne and Sydney and gained the FRACP in 1993. He work at Nepean Hospital, at Penrith Child and Youth Mental Health Service and in private practice in Penrith and have raised a family of four children.
He has been studying the effects of stimulant medication in children with ADHD since 1996. The initial period of weight loss associated with the appetite suppression that occurs on a stimulant leads to transient slowing of growth and in the longer term, to slower progress through puberty  . Stimulant medication improves the symptoms of ADHD, enhancing motivation; it also stabilises the negative mood in oppositional defiant disorder.
