Current projects:

  • Viking metalworking in Dublin (with National Museum of Ireland)
  • Roman and medieval silver production and refining
  • The Tudor Mint at the Tower of London (with Harriet White and Megan Gooch, Historic Royal Palaces)
  • Cultural history of chemistry in the Middle Ages
  • Romanisation of Iron Age precious metals
  • Medieval music wire
  • Medieval high-lead glass (with Bernard Gratuze, CNRS Orléans)
  • Metalworking at Earl's Bu, Orkney (with Colleen Batey, University of Glasgow)
  • The Great Barn at Harmondsworth and its agricultural history

She chairs several Conservation Area Advisory Panels for the London Borough of Hillingdon, is secretary to the Friends of the Great Barn at Harmondsworth (who manage the building on behalf of English Heritage) and is involved with the HLF-funded project at Cranford Park.

She is jointly supervising a PhD student, and is a member of the Early Glass Technology Research Network (EGTRN).
