Rosina Lozano has a particular interest in Latino cities in the United States and has enjoyed taking an active role in the Princeton-Mellon Initiative in Architecture, Urbanism, and the Humanities, which has enhanced her research and teaching of this topic.  

Lozano's doctoral training at the University of Southern California under the guidance of Los Angeles historians George Sánchez and Bill Deverell fostered her enduring interest in historically-Latino cities. Viewing the more recent demographic changes to cities along the East Coast has deepened her interest in how Latinos shape the urban experience more broadly. She explores both phenomena in her undergraduate and graduate courses at Princeton. 

Prof. Lozano teaches courses in the history department—including an upper division undergraduate history course, Latino Urban History, which investigates the history of Latinos in the cities of Los Angeles, Chicago, New York, and Miami. Lozano uses the urban environment as a way to better understand Latinos as a whole. It is in these urban spaces that different Latino national groups frequently interact and support each other’s community interests. They also at times clash in these spaces and jockey for their own community’s benefits. Aside from comparing national origins, the course also looks at the constantly shifting understandings of race, gender, immigration status, and class as related to Latinos. 

Lozano teaches a graduate seminar in the history department on Comparative Race and Ethnicity in the United States, which includes a significant focus on inter-ethnic and cross-racial interactions in urban settings across the United States.
