My research and teaching focus primarily on the history of the US-Mexico borderlands and race and ethnicity in North America. I teach lecture and seminar courses on a variety of topics related to these fields, including research seminars on North American borderlands at the graduate and undergraduate levels. I eared my Ph.D. at the University of Texas at Austin in 2001. My first book, Border Citizens: The Making of Indians, Mexicans, and Anglos in Arizona (University of Texas Press, 2007), examines how racial classifications and identities of the diverse indigenous, mestizo, and Euro-American residents of Arizona’s borderlands evolved as the region was politically and economically incorporated into the United States. I have published essays in journals such as The Western Historical Quarterly and The Latin American Research Review. I am currently working on a book on the history of the US-Mexico borderlands from the late eighteenth century to the present, which is under contract with Yale University Press and is to be published in cooperation with the Clements Center for Southwest Studies at Southern Methodist University, where I was senior fellow in 2016–2017.
