Duncan started out as a biomathematician and then worked as a graphic designer before devoting himself to medieval history. Following an Open University Arts Foundation at Liverpool in 1994 he did a BA in Medieval Studies at the University of Birmingham, where he also completed his PhD (on social transitions in early medieval south-western Britain) in 2002. He held a British Academy Post-Doctoral Fellowship during 2003-6, was elected to the council of the English Place-Name Society in 2005, and was a Visiting Lecturer in Medieval History at Birmingham 2006-10.
Duncan is a Research Associate on the Leverhulme-funded Profile of a Doomed Elite
project with Stephen Baxter
and Chris Lewis
His other research interests include English place-names and personal names (he is writing a dictionary of Devon place-names for the EPNS ‘Popular Series’) and Anglo-Saxon manumissions and guilds (including the preparation of editions for those from post-Conquest Exeter). He retains an interest in the development of the early medieval Church, land-units and patterns of landscape organization (not just in Britain), but this is on the back-burner at the moment.
