Rosina Lozano is a historian of United States history with a research and teaching focus on Latino/a/e history, the American West, migration and immigration, and comparative studies in race and ethnicity.

Lozano's first book, An American Language: The History of Spanish in the United States (University of California Press, 2018), is a political history of the Spanish language in the United States from the incorporation of the Mexican cession in 1848 through World War II, with some discussion of the following decades and present-day concerns. The nation has always been multilingual, and Spanish-language rights, in particular, have remained an important political issue into the present. The book is organized in two parts. The first five chapters argue that Spanish was a language of politics in the U.S. Southwest following the U.S. takeover. The second half of the book transitions to exploring the multifaceted use of Spanish in the twentieth century as it became a political language that instigated local and national political debates related to immigration and Americanization and aided the hemispheric interests of the nation.

An American Language received the PROSE award in Language and Linguistics (2019) and the First Book Prize from the Immigration and Ethnic History Society. Lozano was featured on Al Punto with Jorge Ramos and has given numerous academic and public talks about her book.

Lozano is working on a second book, tentatively titled Intertwined Roots: Mexican Americans and Native Americans in the Southwest, which tells the story of the ever-changing relationship between Mexican Americans and Native peoples from 1848 through the 1970s. The results of U.S. policies for each of these groups are well known separately, but Intertwined Roots considers them relationally, never forgetting that their connections preceded these policies and continued to form independent of them, too. Through the comparison, the book also explores the impact of state and federal politics on ethnic identities. Triangulating the analysis of Anglos, Mexican Americans, and Native Americans offers the opportunity to understand how local and state power has shaped the Southwest against the backdrop of federal policy.

Lozano has received fellowships from the Huntington Library and the New Mexico Office of the State Historian to aid her research. During the 2012-2013 academic year, Lozano held a postdoctoral fellowship from the National Academy of Education/Spencer Foundation that she completed at the Center for Comparative Studies in Race and Ethnicity (CCSRE) at Stanford University.

At Princeton, Lozano is associated with the Program in Latino Studies, the Program in American Studies, and the Program in Latin American Studies.


Lozano joined the Princeton faculty in 2013 and has taught courses including: Becoming Latino in the U.S. (Latino History); Urban Latino History; Borderlands, Border Lives; Comparative Race and Ethnicity in the United States; History 280, 500, and 590; and a History 400 course called Sound, Immigrants and the American West. She plans to teach courses on: the history of immigration and migration; the undocumented; and race, empire, and education in upcoming semesters. Lozano is a faculty adviser in Whitman College and has received the Phi Beta Kappa Teaching Award (2019) and the President's Distinguished Teaching Award (2023).
