Sarah Muir is Term Assistant Professor of Anthropology at Barnard College, Columbia University. Her work examines the practical logics of economic investment, ethical evaluation, and political critique, with a particular focus on social class and financial crisis. Situated at the intersection of semiotic, political-economic, and historical anthropology, her research is grounded in ethnographic fieldwork in Buenos Aires, Argentina. She is currently finishing a book manuscript entitled The Work of Suspicion: Engendering Capital, Routinizing Critique, which examines the consolidation of a national middle-class public in the aftermath of Argentina's 2001/2 financial crisis. She is also researching a new project called Corrupted Futures: Pension Politics, Financial Ethics, and the Reckoning of Kinship, which interrogates struggles over the restructuring of pension plans, conceptualized as key institutions of intergenerational investment and social obligation.
