Biography
Gary graduated from the University of Stirling in 2009 with a BSc (Hons) in Psychology. As part of his degree he spent one year studying at the University of Sydney on a study abroad program. He is currently working towards his PhD in the Institute of Criminal Justice at the University of Portsmouth and is supervised by Dr Becky Milne. His research aims to provide a frontline examination of how witnesses and victims of crime actually first describe a suspect. He will be working closely with Hampshire Constabulary to examine what actually happens at the scene of an incident.
In addition to his studies, Gary has held a number of research associate positions which have been funded by the Technology Strategy Board and the Economic and Social Research Council. In 2012 he worked with Prof Amina Memon (Royal Holloway, University of London), Dr Becky Milne and Dr Daniel Wright (Florida International University) on developing national guidelines on what the police should say to witnesses before, during, and after an identification parade. Most recently he has been working for Dr Anne Hillstrom, Dr Lorraine Hope and Dr James Sauer, looking at whether providing training can improve face matching performance. Gary is also a member of the South East Eyewitness Network (SEEN).
