My research is interdisciplinary, drawing on palaeoecology, environmental archaeology, radiocarbon dating and Bayesian modelling. I am interested in chronology, the archaeology of the Norse North Atlantic diaspora and circumpolar hunter-fisher-gatherers in North America. In particular, I seek to illustrate how these groups impacted/interacted with their environment and how their palaeoenvironmental traces can be used to construct robust chronologies. Methodologically, this work draws me to small depositional settings recording localised environmental signals. When intimately associated with archaeological sites, such deposits are rich archives of chrono-cultural information. Currently, I am working on materials from the Port au Choix and L’Anse aux Meadows National Historic Sites.
