Scientifically I am interested in understanding human intelligence and cognition. I tackle this central question from both psychological and biological perspectives (particularly using pharmacological methods). A significant part of this approach is to better understand the cognitive effects of a wide range of pharmacologically active substances ranging from illicit drugs to herbal and nutrient medicines.
From a practical perspective I am interested in improving emotional competencies in educational settings, particularly primary and secondary schools.
I contributed and lead a team who wrote the National IQ tests for Australia and New Zealand (Channel 9). I was on the scientific advisory panel for the establishment of the International Society for Intelligence Research and have also sat on the Psychology panel of the World Economic Forum. My team was also involved in the evaluation of the road-side saliva tests for illicit drugs for motorists-first introduced in Victoria Australia.
