He was appointed Managing Director of the support services division (DSSD) in 1995. Two years later, he led the successful buy-out of DSSD from DERA to form Comax Secure Business Services Ltd. He subsequently led the team which negotiated the sale of Comax to Amey plc.
In 2005, Love became Chief Executive of QinetiQ, as the company moved to IPO. In October 2009, Love resigned his position after an official report into the crash of an ageing British Nimrod Maritime Patrol Aircraft over Afghanistan in 2006, which killed 14 people, found that QinetiQ bore some of the blame for the mistakes that led to the crash.
Love then joined LGC as Chairman.
He is on the Board of STEMNET (Science, Technology, Engineering and Mathematics Network), the Advisory Board of SEMTA (Sector Skills Council for Science, Engineering and Manufacturing Technologies) and is a Principal at the Chertoff Group (a strategic advisory group focused on security, intelligence and government services).
Graham is also chairman of Racing Green Cars, Eversholt Rail Group and SLR Consulting Group.
