I am Professor of Social Anthropology at the University of Manchester, and co-Director of the ESRC Centre for Research on Socio-Cultural Change (CRESC) where I covene the research theme on ‘Topologies of Social Change’ - an inter-disciplinary group interested in the politics of space, time and matter. I am currently working with Hannah Knox on an ethnography of roads in the Andean and Amazonian regions of Peru. Our almost finished book - Precarious Infrastructures - tracks the material, moral and social controversies produced by a volatile mix of engineering expertise, transnational capital and territorial politics. We are particularly interested in how road construction projects mobilise spatial and temporal imaginaries. Roads are field sites that allow for the empirical study of trans-local places that register histories of travel and of settlement, and that draw together the preoccupations and speculative investments of multilateral funders, international trade and local enterprises. Since October 2010 I have also been working on a new ethnographic project entitled Unsettling the State: Law, Engineering and Regional Government in Cusco, Peru. This is a collaborative project in a research team of six ethnographers, which I run together with Deborah Poole (Johns Hopkins University) that looks at how the ambiguities that technical and legal knowledges create and sustain are mobilised in the exercise of state power. The tropes of temporality and community are central to this work.
