Eric Morier-Genoud is Senior Lecturer on Queen’s Belfast University, United Kingdom. Founder and former Editor-in-Chief of the Social Sciences & Missions Journal, he published last year the monograph Catholicism and the Making of Politics in Central Mozambique, 1940-1986. On this interview, professor Morier-Genoud, tells about his academic trajectory and the itineraries that led his interests for missionary activities on the African continent. The research objects and contacts allowed him to transit between History and Social Sciences throughout his career. His innovating questions offer instigating points concerning the relations amongst colonialism, science and religion. Thus we invite the readers to follow the stories of African missionary images or the dilemmas left by the civil war in Mozambique, as ways of thinking about the histories of anthropology.
