Professor of Developmental Psychopathology at the University of Cambridge, Simon Baron-Cohen has made several ground-breaking contributions to science. He formulated both the mindblindness theory of autism and the prenatal sex steroid theory of autism. He has also developed psychometric scales such as the Autism Spectrum Quotient that discriminate high-functioning autism. This was recommended by NICE as a ‘red flag’ for autism. Professor Baron-Cohen has published books for both parents and practitioners and made two BAFTA-nominated DVDs for teaching people with autism. He is also Co-Editor in Chief of Molecular Autism, and President of the International Society for Autism Research.
