Tim's research is about our ability to recognise and identify people’s faces. His current research is focussed on factors that affect the reliability of eyewitness identification. Previously, he has worked extensively on 'face-space' models of face recognition, with emphasis on the roles of facial distinctiveness, ethnicity and caricature. Other projects have included work on rehabilitation of face memory after brain injury and exploring the structure of our knowledge for familiar people. He regularly provides expert advice on identification issues in criminal cases.
