I am the author of numerous scholarly papers and two monographs. Research interests include the environmental history and historical, cultural, and political ecology of the colonization of the Americas. I have made various contributions to the theorization of colonialism and landscape, the critique of neo-environmental determinism, to understanding pre-colonial and colonial agriculture and environmental change in Mexico, and to revealing African contributions to establishing cattle ranching in the Americas. With the publication of Black Ranching Frontiers: African Cattle Herders of the Atlantic World, 1500–1900 (Yale University Press, 2012) and a 2012-13 Digital Innovation Fellowship from the American Council of Learned Societies, my interests have increasingly aligned with a growing number of scholars from multiple disciplines working from the perspective of Atlantic History and using the tools of the Digital Humanities. I currently teach at Louisiana State University.
