Biography and Interests
Geoff was educated at Oxford, Cardiff and London. Prior to joining the unit he held posts in the MRC Social Psychiatry Unit and in the South Glamorgan Health Authority. He began his research career working on a survey of children's accidents in Cardiff. From there he went on to work on the Cardiff and Camberwell psychiatric case registers. He has worked on the Present State Examination (PSE) and the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). He was for several years a member of the WHO steering committee for SCAN and helped co-ordinate the international field trials.
Since joining the unit he has made extensive use of The West of Scotland Twenty-07 study often in collaboration with external researchers.
His current research interests concern the relationships between cognition, material circumstances and health. These interests include a focus on measures of reaction time as indicators of cognitive ability and on their relation to health outcomes.
He is an associate member of the Edinburgh based Centre for Cognitive Ageing and Cognitive Epidemiology.
