JM has been working continuously in archaeology for over thirty years. He set up John Moore Heritage Services taking over the services formerly offered by the Oxford office of an Edinburgh based company, of which he was a director. During the three years with that company he helped establish offices in England to broaden the base of the Edinburgh based company, being responsible for contracting services. Prior to that JM held responsibility for all fieldwork projects undertaken by a large archaeological unit over a seven year period. When funding for archaeological projects was changed from being Government based to being developer funded John was the first archaeologist specifically appointed within an archaeological organisation to seek commercial projects. As such he has a broad base of dealing with different types of projects and designing suitable mitigation solutions in partnership with designers, architects and engineers.
For three years JM held a fellowship at the British Institute of Archaeology at Ankara where he directed a major excavation of Islamic and Hellenistic levels of Tille Hoyuk as part of a large-scale international project. He has also worked in France, directed a fieldwork project in Ukraine and undertaken consultancy work in Germany.
He has written, and co-authored, three books on the results of major excavations and has produced numerous articles. He is a Member of the Institute for Archaeologists.
