Kelvin Ng is a PhD candidate in the Department of History at Yale University. His research work brings together the social history of migration and the intellectual history of internationalism in four linked Indian Ocean spaces: British India, Republican China, British Malaya, and the Dutch East Indies. His dissertation project engages with three intertwined strands of anti-imperial thought communist internationalism, pan-Islamism, and anti-caste radicalism which transformed colonial Asia. His research interests more broadly include political economy, intellectual history, histories of migration, and histories of the left. Kelvin graduated summa cum laude from Columbia University with a B.A. in History and Ethnic Studies, and received a M.A. in Asian Studies from the Weatherhead Institute at Columbia University. At Yale, he is a graduate associate at the South Asian Studies Council and the Council for Southeast Asian Studies.

His published academic work has appeared in Comparative Studies of South Asia, Africa and the Middle East , South Asian History and Culture , and South Asia .
