Katherine Benton-Cohen is associate professor of history at Georgetown University, where she teaches courses in nineteenth and twentieth century US history. Her specialties concern immigration, race, gender, the borderlands, and the American West. Her first book, Borderline Americans: Racial Division and Labor War in the Arizona Borderlands (Harvard University Press, 2009), uses Cochise County, Arizona, to examine the history of race in America. She is currently completing a book on the origins of modern immigration regulation in the Dillingham Commission of 1907-1911, the largest study of immigrants in American history.
Benton-Cohen has received numerous research fellowships and awards from the National Endowment for the Humanities, the Woodrow Wilson International Center for Scholars, and elsewhere.
