Majapra joined Tufts History Department in 2008. His research is in modern South Asian and German history, with a special interest in transnational approaches and postcolonial critical perspectives. His most recent book is Age of Entanglement: German and Indian intellectuals across Empire, which compared and connected the rise of modernism in Germany and India in the period of British world power. Manjapra's work crosses national and imperial boundaries and pursues a multi-focal study of intellectual history, the history of science and scholarship, and the history of nineteenth and twentieth imperialism and international politics. He has written on anti-colonial cosmopolitanism, trajectories of Marxism, artistic and philosophical modernism, Orientalism and the politics of cross-cultural encounter.
