Professor of History

Matthew S. Hopper serves as a Professor of History at California Polytechnic State University, San Luis Obispo, where he specializes in African and Indian Ocean history. His book, "Slaves of One Master: Globalization and Slavery in Arabia in the Age of Empire" (Yale University Press, 2015), examines the history of the African diaspora in Arabia and the Gulf and was recognized as a finalist for the Frederick Douglass Book Prize in 2016.

Hopper has held postdoctoral and visiting fellowships at the Gilder Lehrman Center at Yale University, the Institute for Advanced Study in Princeton, the University of Cambridge, King’s College London, and The Africa Institute (Global Studies University) in Sharjah. His research has received support from organizations such as the Social Science Research Council, Fulbright-Hays, the National Endowment for the Humanities, and the British Academy. His scholarly contributions have been published in journals such as Annales, Itinerario, and the Journal of African Development.  He is currently a member of a team working to incorporate the Indian Ocean into the Transatlantic Slave Trade Database (SlaveVoyages.org) with the support of a grant from the National Endowment for the Humanities.

Hopper earned his Ph.D. in History from UCLA and holds dual master's degrees: one in African Studies from UCLA and another in History from Temple University.
