I am anthropologist interested in the violent social process of undocumented migration from Latin America to the United States. I direct the Undocumented Migration Project (UMP), a long-term study of clandestine border crossing that uses a combination of ethnographic, archaeological, visual, and forensic approaches to understand this phenomenon in a variety of geographic contexts including the Sonoran Desert of Southern Arizona and the Mexico/Guatemala border. The UMP, through our Colibri Initiative, also works directly with families of missing migrants to help identify and repatriate the remains of people who have died while migrating. My first book, The Land of Open Graves: Living and Dying on the Migrant Trail (UC Pres 2015) focused on the impacts of the U.S. border enforcement policy known as “Prevention Through Deterrence” that has led to the deaths of thousands of people in the Arizona desert. My second book, “Soldiers and Kings” (forthcoming 2023 from Viking Press), examines the everyday lives of Honduran smugglers moving migrants across Mexico. I am currently working on a book about the praxis of photoethnography and also conducting ethnographic and forensic fieldwork in Mexico and Honduras focused on the subject of missing migrants. I hold a split faculty position in the Department of Chicana/o Studies and the Department of Anthropology. I am also affiliated with the Cotsen Institute of Archaeology, which is where my research lab is located.
