Leo R. Chavez is a Full Professor of Anthropology at the University of California, Irvine. He received his Ph.D. from Stanford University. He has published extensively on 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.” Of late, he has examined the changing dimensions of citizenship and belonging as a result of migration, fertility declines in industrial nations, and the on-again, off-again demand for immigrant labor. In addition, he has paid particular attention to the way media spectacles work to provide a way of knowing about the various members of our ever-changing societies. Finally, Chavez has examined obstacles to the integration of the children of immigrants, both in the United States and Europe. Although much of his research focuses on the United States, he has also spent considerable time in Latin America and Europe, especially Spain. He has sailed on the Semester at Sea program as both a student and faculty member.
