Professor Johnson has conducted research on the intersection of religion, race, and colonialism in the Americas and throughout Atlantic geographies (Africa, Europe, the Caribbean, and the Americas) over the past five centuries. His analysis of this material foregrounds the architecture of racial states and settler colonialism; the colonial formation of what scholars tend to name “modernity,” and the increasing role that the national security paradigm has played in shaping the relationship between religion and the state. His first book, The Myth of Ham in Nineteenth-Century American Christianity, focuses on the problem of religious hatred as a particular formation of anti-Blackness during a pivotal era of African American Christianization. His second book, African American Religions, 1500–2000, provides a narrative and theoretical account of religion and racial formation to explain the linkage of Atlantic empires and democratic freedom. He began this project in an attempt to move beyond limiting the account of Black religion to the problem of slavery or to conceptions of race that are divorced from a theoretical appreciation for the historical reality of colonialism, particularly as a phenomenon of the United States. Professor Johnson's graduate and undergraduate courses examine the relationship of religion and politics with particular attention to sexuality & gender, race & colonialism, and the corresponding genealogies of freedom and modernity. He also co-edits the Journal of Africana Religions, which is devoted to publishing transnational, interdisciplinary research on religion within Africa and throughout the global Black diaspora.
