Her research focuses on cultures of nature and interrogates the ways in which human relations with the natural world are imagined and practiced in the conduct of science, governance and everyday life. She has published widely on the theoretical and political implications of these questions and is an acknowledged pioneer in what have become known as 'more-than-human' modes of enquiry, concerned with the material and ecological fabric of social life and the politics of knowledge through which this fabric is contested and re-made historically and today. Of particular interest are those situations and events in which different ecological epistemologies are brought into conflict. This informs a more recent body of work interrogating the relationship between science and democracy particularly in terms of the nature of evidence in the practices of environmental science and law and the role of expertise in environmental governance, now widely mediated by risk modelling techniques. Her work is characterised by (i) a sustained engagement with a range of intellectual resources in philosophy, political theory and those disciplines most concerned with the study of material culture (notably cultural geography, archaeology, anthropology and science and technology studies); and (ii) a commitment to experimental and collaborative research practices that bring the different knowledge competences of social and natural scientists into play with those of diverse local publics that emerge in consequence of living with environmental risks and hazards. It has been supported by a variety of funding bodies including various UK Research Councils, NGOs and Government agencies, as well as charitable foundations such the Mellon Foundation.
