My research interest has evolved from history of infectious diseases in Africa to the history of global health in Africa. Basically, to use the history of global health as an analytic tool to understand disease crises in Africa. I am interested in the continuities and changes in patterns of responses of Africans and global health structures to health crises, such as the Ebola disease crises in Africa. In understanding the burden of diseases in Africa; emerging and recurring, failure and dynamics of interventions, it becomes important to revisit the paths of colonization of Africa and how the global economy evolved from these processes. A global lens allows me to see how economy, politics, science intertwined with diseases and the bid to eliminate it.
