I am an experimental psychologist and neuropsychologist , now retired from full time employment (2008). I was appointed to professorial chairs at Goldsmith's College, University of London (1991) and University College London (1996). I helped to launch the ESRC-funded research centre DCAL (Deafness, Cognition and Language Centre), in 2005. I remain an emeritus professor at UCL and, in addition to a PhD (London, 1979) holds an honorary research position at Kings College London (Institute of Psychiatry) and an honorary doctorate from Linkoping University, Sweden (2007).
One of my specific research aims, over thirty years, has been to understand the psychological and neural bases of speechreading, and, in addition to over 150 or so peer-reviewed journal papers, I have edited or co-edited several volumes dedicated to putting speechreading on the map as a topic for psychological and interdisciplinary research.
As an expert on speechreading I have worked to develop a consistent and scientifically based approach to the forensic uses of lipreading, as advisor and as an expert witness on landmark cases including R. V Luttrell et al., a case now cited in authoritative legal reports on forensic evidence. With this in mind, I collaborated with Laraine Callow (Director, Deafworks) to develop a unique innovative training course for Deaf forensic speechreaders in 2008. This course was supported by an ESRC business grant.
