David has spent most of his career at the Public Record Office (PRO) and The National Archives (TNA). He joined the PRO in 1974, after completing a history degree at the University of London. David completed his doctorate whilst working at the archive, and became a part-time lecturer at University College, London in 1979. He continued to juggle his work at the PRO with lecturing (until 1989) and his varied research interests. These interests include Shakespeare, forgeries and fraud in archives, historic churches and the sensitivity review of digital records.
In 2005 David became Director of Technology at TNA, until his retirement in July 2014. Since December 2014 he has been a Visiting Professor at Northumbria University’s iSchool.
