Delphine Neff is a research director at the NIMBE/LAPA. She develops research projects on understanding the transformation of ancient corrosion layers during desalination treatments as well as their interaction with organic compounds applied as protective coatings. She’s a member of the French society CEFRACOR and a member of the EFC STAC and chairwoman of the WP21 on ‘historical and archaeological artefacts”. Sabrina Grassini is Associate Professor of Applied Physical Chemistry at the Department of Applied Science and Technology, Politecnico di Torino, Italy. Her main research works are devoted to Conservation of Cultural Heritage: studies of degradation processes on metallic artifacts and development of tailored strategies for restoration and conservation; she also develops studies on innovative plasma technologies for protection of metallic artifacts. She is member of the Italian Association of Metallurgy and Secretary of the EFC Working Party 21-Corrosion of Archaeological and Historical Artifacts. David Watkinson teaches conservation theory and practice, focusing his research on understanding and controlling the corrosion of ferrous metals. His research into desiccated storage of unstable iron underpinned the conservation of Brunel’s iconic steamship SS Great Britain. In 2010 he was awarded the Plowden Medal for his innovative research and contributions to the conservation profession. Having served widely on committees and grant awarding bodies he is currently vice-chair of the EFC WP21 on ‘Historical and Archaeological Artefacts”. Nicola Emmerson teaches conservation and heritage science theory and practice at Cardiff University. She researches the corrosion and conservation of heritage metals, particularly iron, with a focus on anticorrosion methods and materials and their application to historic artefacts. Nicola is the Chair of the Institute of Conservation Metals Group and Assistant Coordinator of the International Council of Museums Committee for Conservation Metals Working Group.
