Our usual host, Dr. Philip Gooding (IOWC, McGill), is our interviewee this week, answering a few questions about his first monograph, On the Frontiers of the Indian Ocean World: A History of Lake Tanganyika, c.1830-1890 (Cambridge UP, 2022) with our producer, Sam Gleave Riemann. As well as introducing the book to listeners who haven't had a chance to read it yet, they answer a handful of questions that Philip didn't have time to address at his book launch, considering the role of Christian missionaries and Muslim merchants, narratives of continuity and change, and his varied methodologies. Philip earned a PhD in History from SOAS London in 2017. He joined the Indian Ocean World Centre as a Postdoctoral Fellow in 2018 and since then has published a number of articles on East African and Indian Ocean history, co-edited two multi-author volumes, and served as associate editor of the Journal of Indian Ocean World Studies.
