His first book, Citizenship and Belonging: Germans, Argentines, and the Meaning of Ethnicity in Buenos Aires, 1880-1930, is currently under review. Focusing on education, religion, and social welfare, it charts German-speaking Argentines’ competing visions of Germanness and Argentine belonging. He is also the co-editor of Making Citizens in Argentina (University of Pittsburgh Press, 2017) and Entangling Migration History: Borderlands and Transnationalism in the United States and Canada (University Press of Florida, 2015).
