Haimanti Roy specializes in the political and social history of colonial India and modern South Asia. Her first book entitled Partitioned Lives: Refugees, Migrants, Citizens in India and Pakistan, 1947-65 (Delhi: Oxford University Press, 2012) examines issues of territoriality, identity, migration and citizenship, and the subsequent re-ordering of national identities of ordinary men and women in post-Partition India and East Pakistan (present day Bangladesh). She is currently working on a social history of certificates and documents in twentieth century India.
Roy has previously taught at the University of Cincinnati, Massachusetts Institute of Technology and at Georgia Institute of Technology. At the University of Dayton, she teaches courses on Gandhi, The British Empire, Indian Cinema, Gender and Sexuality in South Asia.
