Simon Baron-Cohen FBA is Professor of Developmental psychopathology at the University of Cambridge in the United Kingdom. He is the Director of the University's Autism Research Centre, and a Fellow of Trinity College. He has worked on autism, including the theory that autism involves degrees of mind-blindness (or delays in the development of theory of mind) and his later theory that autism is an extreme form of what he calls the "male brain", which involved a re-conceptualisation of typical psychological sex differences in terms of empathising-systemising theory.
