I teach at the Department of History, University of Delhi, and specialize in the history of modern India. My research interests include histories of frontiers and borderlands, the political economy of colonisation, the figure of the primitive, colonial state formation and law, and the histories of tribal/peasant rebellions. I have studied at the University of Delhi, Jawaharlal Nehru University and the School of Oriental and African Studies, University of London. I have been a Commonwealth Scholar at the School of Oriental and African Studies, London, a British Academy-AHRC-ESRC Visiting Fellow at the School of Oriental and African Studies, London, and a Fellow at the Nehru Memorial Museum and Library, New Delhi. My work has been published in academic journals including the Indian Economic and Social History Review, Studies in History, the Economic and Political Weekly and the Modern Asian Studies and in anthologies. My monograph, Becoming a Borderland: The Politics of Space and Identity in Colonial Northeastern India was published in 2011 by Routledge: London and Delhi (Paperback Reprint with a new introduction: 2014, 2017). I have been the recipient of several fellowships including the Harold Hyam Wingate Trust, ICSSR, ICHR, and the Charles Wallace India Trust.
