My area of research is francophone West Africa, with interests ranging widely across social, cultural, political, and environmental history. As an historian, I do mostly empirical research, which means working in archives in African countries, such as Mali, Burkina Faso, and Senegal, and France. However, my research also draws heavily on interviews, or oral history, conducted with hundreds of individuals in West Africa and France.
My first book, Islamization from below, explored the ways in which Islam spread into southern Mali under French colonial rule, c. 1880s-1960. This research was based largely on interviews with rural peoples in small villages across southern Mali. In recent years, I have done research on the Cold War period and changes in African political thought. Along these lines, I'm currently completing a political biography of the African revolutionary Thomas Sankara (1949-1987). My ensuing project focuses on climate refugees (between the West African Sahel zone and Europe), and will be more of an environmental history of the period from the 1970s to the present. Outside of this research, I also regularly contribute political analyses of recent events to such websites as African Arguments and Think Africa Press.
I teach courses on African history, with special emphasis on the colonial and post-colonial periods. I also offer courses on French and Islamic history.
