Nicole Harlaar is a PhD student at the Institute of Psychiatry, London, UK. She is interested in the nature and mechanisms that mediate genetic and environmental risk factors for cognitive and learning disabilities and in trying to piece together how these processes change through the school years. Currently, she is examining these issues in a population-based longitudinal study of twin children in the UK Twins Early Development Study (TEDS).
