Professor Chavez's research examines various issues related to transnational migration, including immigrant families and households, labor market participation, motivations for migration, the use of medical services, and media constructions of "immigrant" and "nation." His books include Shadowed Lives: Undocumented Immigrants in American Society (Harcourt Brace Jovanovich 1992, 1997 2nd edition), which provides an ethnographic account of Mexican and Central American undocumented immigrants in San Diego County, California. Covering Immigration: Popular Images and the Politics of the Nation (University of California Press 2001) examines representations of immigrants in the media and popular discourse in the United States through the lens of magazine covers and their related articles. His newest book is The Latino Threat: Constructing Immigrants, Citizens and the Nation (Stanford University Press 2008), which examines issues of anti-Latino discourse, struggles over the meaning of citizenship, and role of media spectacles in society in relation to the politics of reproduction, organ transplants, the Minuteman Project, and immigrant marches and protests. The Latino Threat, 2nd Edition, released in 2013. Recent medically related articles include "Beliefs Matter: Cultural Beliefs and the Use of Cervical Cancer Screening Tests;" and "Immigration and Medical Anthropology" (2003). See also, "Culture Change and Cultural Reproduction: Lessons from Research on Transnational Migration" (2006); and “Commentary: The Condition of Illegality” (2007).
