I specialize in history of medicine and colonial and global history. I trained in history at the Centre for Historical Studies, Jawaharlal Nehru University in New Delhi, where I completed an M.A. and an M.Phil. After being awarded the first Roy Porter Memorial Studentship, I completed my PhD thesis on the history of  the interactions between tropical medicine, the colonial state, and colonial enclaves in India at the University College London. I have thereafter worked as a researcher at the University of Warwick and then taught History of Medicine at Yale University and Urban and Colonial History at Leicester University. In 2011 I was awarded the Wellcome post-doctoral fellowship for my project on a history of the Indian pharmaceutical industry in the twentieth century.
