Sujit Sivasundaram is Professor of World History at the University of Cambridge and Fellow in History at Gonville and Caius College, Cambridge. 'Waves Across the South: A New History of Revolution and Empire' is his third book. It was awarded the British Academy Book Prize in 2021 and Jerry Bentley Book Prize in World History in 2022. This book and his broader work draws the Pacific and Indian oceans into a conversation around histories of the environment, the history of race, imperial history and the history of science. 'Waves Across the South' included discussions of the histories of Australia, Aotearoa/New Zealand and the Pacific world in the late eighteenth and early nineteenth centuries. He is currently President of the Pacific Circle, a group of scholars devoted to the study of knowledge and environment across the Indian and Pacific Oceans. He is now working on a long environmental history of the Indian ocean and on an urban history of Colombo, a multiply-colonised and engineered city in the centre of the Indian Ocean, a transit point between Europe and Australia, in addition to other maritime routes.
