Currently the Technical Advisor for LGC Digital Investigation Unit and have been so for the last three years. Been involved in Digital Forensics since Nov 1990 when I was a member of Thames Valley Police Fraud Squad and developed investigating company computers as part of my case work. Prior to the Police I was in Radio Electronics in the Royal Navy. Over the last 27 years I have been involved with various Digital Forensics units including the Police, commercial companies and a UK Law enforcement National Unit. As the Technical Advisor for LGC one of my main responsibilities is the DIU ISO 17025 accreditation which involves the validation of the Digital Forensic tools used.
