My areas of specialization include late 20th and 21st century US literatures, border studies, hemispheric studies, immigration studies, and fiction of the US Southwest. I am the author of Border Fictions: Globalization, Empire, and Writing at the Boundaries of the United States (U. of Virginia Press, 2008), which explores cultural productions about the U.S. borders with Canada and Mexico from the perspective of hemispheric studies. I am also the editor of Globalization on the Line: Culture, Capital, and Citizenship at U.S. Borders (Palgrave, 2002). In addition, I have published essays on reality TV, comparative immigration studies, comparative border studies, transnational adoption, studies of the U.S.-Mexico and U.S.-Canada borders, and on the internationalization of US American studies.
