Materials analysis is the core of archaeological science; but for a fuller understanding, science must be integrated with social sciences and humanities, thus opening new ways to understand the past, and new opportunities to overcome present and future challenges. My research work, past, present and prospective is focussed on six main areas: (i) reconstruction of ancient technologies (e.g. metallurgy, ceramics, etc.), (ii) artefacts, technology and innovation, (iii) integration of social science theories with scientific techniques to enhance effectiveness of scientific methods, (iv) history of technology, (v) application of scientific techniques to conserve artefacts and sites and (vi) public engagement through heritage science including exhibitions. This work is pursued through excavations, museum-based projects, laboratory investigations (optical microscopy, SEM-EDS, EPMA, WD-XRF, (LA)-ICP-MS, etc) and experimental work, bringing together natural and social sciences with humanities.
Selected current projects:
- Archaeometry and social formation in southern Africa (British Academy Global Professorship Programme)
Application of integrated archaeological science techniques (materials analysis, bioarchaeology and remote sensing) to explore resource provisioning and circulation at Great Zimbabwe and beyond.
- Archaeological science and globalisation: crucibles and metallurgical artefacts from Great Zimbabwe World Heritage site (with Paul Lane and Marcos Martinon-Torres, Cambridge) (Royal Society Mobility Grant)
Application of archaeometallurgical, petrographic and quantitative techniques to characterise crucible fabrics and attached metal processing residues to infer mobility and transfer of ideas between southern Africa and the Indian Ocean.
- Gold and silver circulation during the initial phases of the Atlantic and Indian Ocean trade: Au and Ag coins from the Bom Jesus Shipwreck (University of Oxford, Higher Studies Fund).
Application of trace element geochemistry, lead isotope analysis and quantitative techniques to explore circulation of gold and silver between Latin America, Europe, and West Africa
- Viking Iron Production in Norway (with Per Ditlef Fredrisen, Oslo)
Chemical and mineralogical analyses of slags, ores, tuyeres, and furnace remains from selected Viking iron production sites in Norway
