Research
I study ecological globalisation. My background is in medieval and environmental archaeology, with special interests in the trade of fish, furs and ivory. I am particularly drawn to the complex links between rural producers of the north and (often distant) urban consumers. Thus I am also fascinated by the construction of local (including island) identities and by the causes and consequences of commercialisation (social, economic and ecological). In current jargon I am equally interested in Globalisation and Glocalisation. My work within medieval archaeology also attempts to balance both archaeology’s power as an evidence-based discipline that can challenge primordial misconceptions of the past (that can lead to intolerance) and its value, as a heritage-based subject, to empower the self-determination of communities and peoples.
In methodological terms most of my research has involved the combination of archaeological science, medieval/historical archaeology and history, with the ultimate aim of reconciling archaeology's divergent scientific and humanistic traditions. I started academic life as a zooarchaeologist, but have since been directly or indirectly involved in applying a diverse range of techniques and am better described as a historical ecologist. As a proponent of the holistic study of historical ecology, I am equally interested in the study of ecofacts (bones, plant remains, soils, etc.) and artefacts. Much of my research relates to the study of marine resources, but I am interested in the interface of nature and culture on land and sea.
My collaborative projects range from the SeaChanges Innovative Training Network (led by the University of York), and Catching the Past: Investigating the Legacy of Atlantic Cod Exploitation using Ancient DNA (led by the University of Oslo with funding from the Research Council of Norway) to rescuing the archaeology of reindeer hunting sites melting out of ice patches in Jotunheimen (led by Oppland County Council). I am presently writing up research on trade of walrus ivory as an example of ecological globalisation, and also coordinate the Northern Seas Synthesis, an initiative to harvest the power of archaeological fish bone records for archaeology, environmental history and conservation biology.
I serve as Deputy Director of the McDonald Institute for Archaeological research, as a visiting professor (Professor II) at the Norwegian University of Science and Technology (NTNU) in Trondheim, and as an honorary research fellow in the Centre for Environmental Humanities, Trinity College Dublin. I also serve as an academic advisor, reviewer and/or panel member for a wide range of organisations and publishers, recently including the Arts and Humanities Research Council, The German Research Foundation, The Icelandic Research Fund, Nature and ICOMOS.
