Qualifications and awards: BSc in physics with chemistry (University of Sussex 1971), MSc in archaeology (Institute of Archaeology, UCL 1973) and PhD on Non-ferrous metalworking in England: late Iron Age to Early Medieval (University of London 1992). Churchill Fellowship (1979) for travel to Germany and Scandinavia to study Dark Ages metal and glass working. Fellow of the Society of Antiquaries of London since 1989.
From 1973-2010 I worked at the Ancient Monuments Laboratory, now part of English Heritage, leading its Technology Team from 1981. Our work included identifying remains of past industries and examining and analysing finds from archaeological excavations. I acted as scientific advisor and specialist contributor to many EH- and developer-funded archaeological projects as well as carrying out a range of research projects. In 2011-12 I worked for the Portable Antiquities Scheme as national advisor for Roman finds.
I have taught and supervised students at universities in Britain and abroad, currently at UCL and the Architectural Association, and have run numerous ‘Slag Days’ (hands-on teaching to familiarise archaeologists with industrial residues). I am a member of the Historical Metallurgy Society, the Association for the History of Glass, and the Later Prehistoric, Roman and Medieval Finds Research Groups. I am currently President of AHG, Chair of the RFG, and since 1990 have been joint Honorary Editor of Historical Metallurgy.
I chair several Conservation Area Advisory Panels for the London Borough of Hillingdon and act as secretary to the Friends of the Great Barn at Harmondsworth who manage the building on behalf of English Heritage.
Research interests and current projects
My research interests mainly concern aspects of non-ferrous metal and glass working of the last two millennia, focusing on the British Isles but set within a European context. I am a member of the Early Glass Technology Research Network (EGTRN).
Current projects include:
- Non-ferrous metalworking in Roman Britain
- Viking metalworking in Dublin (with National Museum of Ireland) and in Lincoln (with Letty Ten Harkel, IoA Oxford)
- Roman and medieval silver production and refining
- The Tudor Mint at the Tower of London (with Harriet White, IoA UCL and Megan Gooch, Historic Royal Palaces)
- Romanisation of Iron Age precious metals
- Roman enamelling
- Early medieval brass ingots (with Jonathan Cotton, Thilo Rehren, UCL Qatar, and Ernst Pernicka, CEZ Archäometrie Mannheim)
- Medieval music wire
- Medieval high-lead glass (with Bernard Gratuze, CNRS Orléans)
- The Great Barn at Harmondsworth and its agricultural history.
