Environmental sentinels and the more-than-human practices and politics of sensing the European and North American Arctic


Academic Profile

Oscar is an environmental and cultural geographer interested in the practices and politics of environmental sensing in the European and North American Arctic. His doctoral research investigates how the Arctic has come to be known as a sentinel or 'canary in the coal mine' of global environmental change, applying a material semiotic approach to trace this notion and its effects across different sensing assemblages, from community-based monitoring to citizen science projects and large transnational Arctic expeditions, and their varied efforts to assemble and mobilise concerned publics.

Prior to starting the DPhil in 2019 he completed an MSc in Nature, Society and Environmental Governance at the School. His research followed novel conservation approaches on the Great Barrier Reef, situating these in relation to the wider Australian political climate and a diffuse atmosphere of fear and grief for the future of the Reef. The research focused in particular on the management of the much-maligned Crown-of-Thorns Starfish, and he spent a period as a visiting researcher at the Australian Museum's Lizard Island Research Station.

Oscar's broader research interests include: science and technology studies; more-than-human geographies; behavioural ecology; invasion biology; environmental governance; Inuit Qaujimajatuqangit (Traditional Knowledge); and citizen sensing.
