My post-doctoral work took the question of knowledge and alterity to a different field: that of inter-species relations in scientific research. I studied the conceptual and material relations between humans and other animals in behavioural biology, with a particular focus on researchers who study meerkats. As in the Corsican case, the focus was on the ways in which understandings of similarity and difference emerge from situated interactions, the intersections of materiality, sociality and language, and the ways in which knowing and not-knowing constitute and emerge from social, ethical and political relations.
