Research Interests

My research is interdisciplinary and draws on environmental and archaeological sciences. I generate original palaeoenvironmental data and interrogate archival datasets as a means to ask spatial and temporal questions about the complex nature and legacy of human-environment interactions, farming, biogeographical change and the formation of cultural landscapes. The temporal, geographic and cultural locus of my work is the past two millennia in the North Atlantic (Greenland, Iceland, Newfoundland) and circumpolar North America (Alaska), and the cultural groups therein (Norse, pre-Inuit, Inuit, European). My experiences also cover climate reconstruction, longer-term human-environment interactions and early urbanisation in Auvergne, central France.

I work with data from a variety of sources, including ‘natural’, written and digital archives. A frequent challenge is resolving the complexities of working with ‘sub-optimal’ archives and data. For example, organic deposits (i.e. soils and minerogenic peats) found in close association with sites of human activity are rich sources of palaeoenvironmental and chrono-cultural information, but are often taphonomically complex. Thus, an important part of my cursus has focused on understanding the depositional processes that form these difficult palaeoenvironmental media. Working in circumpolar regions and studying associated cultural groups also presents challenges for constructing robust chronologies. This is a recurrent tension, particularly when realising the potential of legacy data and integrating them into modern archaeological frameworks. Currently, I am CoI with Veronique Forbes (PI) on a SSRHC Insight grant entitled ‘Biocultural and Archaeological Legacies at L’Anse aux Meadows’.
