I am a full time researcher funded by the Wellcome Trust on a Principal Research Fellowship. I am also Professor of Developmental Neuropsychology in the Department of Experimental Psychology. My main research interest is the nature and causes of communication problems in children, especially specific language impairment (SLI), autism, dyslexia and Down's syndrome. To study these conditions, I use methods from linguistics, neurophysiology, genetics and neuropsychology.
