A fascinating guest post today from Dr Tim Grant, Senior Lecturer in Forensic Linguistics at Aston University in the UK, and the Director of the Centre for Forensic Linguistics there. His main research interests are in forensic authorship analysis and in the conversations which occur between attackers and victims in cases of serious sexual assault and rape. He has publications in both of these areas in both psychology and linguistics journals. His consultancy has largely involved the analysis of abusive and threatening communications in many different contexts including investigations into sexual assaults, murder and terrorist offences. It has also included cases of copyright infringement and academic plagiarism.
