David R JefferiesDavid Jefferies has been involved in crime for longer than he cares to think about. He has worked in investigations with the United Kingdom Government, across several departments, and the private sector. Serving as a Justice of the Peace for many yeas has also given him a close-up view of the criminal justice system. He was introduced to deception detection many years ago while undertaking an MA in Fraud Management, starting with Scientific Content Analysis and then branching into behavioural psychology and microexpressions. Having completed training in deception detection with renowned experts in their fields and former FBI operatives, he brings his knowledge of the subjects together in a new way to bring deception detection out of the criminal investigation world and make it accessible in many other walks of life. In addition to his academic qualifications, David is a member of the British Psychological Society and a Fellow of the Royal Society for the Arts. He is also secretary of the Commonwealth Association of Science, Technology and Mathematics Educators (CASTME). When not working on deception detection, he likes to play keyboards and volunteer with a heritage steam railway in his adopted home county of Norfolk. Read More Read Less
