My research interests include the social history of nation-building, race and identity, and political culture in the Americas in the nineteenth century, especially Mexico and the border regions of the United States. I am also particularly interested in the social and cultural history of drinking in the Americas, and the expanding interdisciplinary field of drinking studies, which I have supported through the establishment and co-ordination since 2010 of a Drinking Studies Network based at the University of Warwick. I am currently working on a research project that brings together all these areas of enquiry: a comparative study of the relationship between alcohol consumption, race, and nationhood in the US and Mexico in the nineteenth and early twentieth century. In this comparative research, I am focusing particularly on soldiers' drinking habits in the Mexican-American war, the display of indigenous peoples and material culture in late nineteenth-century International Exhibitions, and the early twentieth-century experiments with Prohibition. Among my future plans for research is a project investigating concepts and practices of liberal citizenship during periods of war in the Americas, taking the Mexican-American war (1846-48) as a starting point.
