A historian of South Asia and contemporary international relations, I joined King’s College London in early 2016, after a Research Fellowship at Emmanuel College, Cambridge and a visiting fellowship at the Graduate Institute, Geneva. My work focuses on the impact of decolonization in South Asia as we know it today, particularly in terms of international politics.

I’m particularly interested in the connections between state-/nation-building and geopolitics, notably in border spaces like the Himalayas and the Indian Ocean. I hold the 2012 the British Association for South Asian Studies annual prize, Cambridge University’s Prince Consort Prize and Seeley Medal 2014 and a British Academy Rising Star Award 2018.

Research interests & PhD supervision

Inter-national and trans-national relations in the post-colonial world
South Asia and the Indian Ocean
Frontiers, borders and borderlands
Decolonisation
State-making and nation-building
Maritime spaces

I have written extensively on Sino-Indian relations and on the strategic borderlands between India, India, Tibet and Burma, most notably in my book Shadow States: India, China and the Himalayas (CUP 2016; awarded the James Fischer Prize 2018 for the best book on Nepal & the Himalayas).

My current research is taking me in two directions. First, I’m currently working on post-colonial India’s practice and imagination of diplomacy and on South Asia and the international order. My second project explore the geopolitics of the Indian Ocean since 1945, at the intersection of the Cold War, decolonization, and the transformation of the ocean into a resource and sovereignty frontier.

I welcome applications from potential PhD students on projects concerning the international history of South Asia, and on north-eastern India and the Himalayas.

Expertise and public engagement

I regularly contribute to debates on the politics and history of modern South Asia, as well as strategic foresight discussions on the region. I intervene in the international press and online media, but also in policy circles, public history events, and cultural institutions from Delhi to Brussels.

I am the founder of NIHSA - the New International Histories of South Asia network, a research and public engagement platform that works to inform understandings and decision-making on South Asia by intervening into public/policy debates with historically grounded analysis on the subcontinent.
