Laurencio Sanguino received his Ph.D. in history from the University of Chicago in December 2012. His dissertation, “The Origins of Migration between Mexico and the United States, 1905-1945,” examines the development and transformation of migration between Mexico and the United States, describing how labor recruitment, trafficking, and enforcement practices changed between 1905 and 1945. His next project will chart how Zamora, Michoacán, was transformed into one of the most important migrant-sending communities in Mexico between 1885 and 1965. It will follow migrants to worksites in Mexico and the United States and describe their interactions with traffickers, migration officers, labor recruiters, employers, and government officials in order to provide readers with a comprehensive understanding of the migratory experience. His work has appeared in a number of edited volumes, including Ciudades mexicanas del siglo XX: Siete estudios históricos (2009) and Civic Hopes and Political Realities: Immigrants, Community Organizations, and Political Engagement (2008).
