Degree in Sociology from the University of Buenos Aires (Argentina); Master in Latin American Studies and PhD in Sociology from the University of Salamanca (Spain). During this stage I have done research stays at the universities of York (Canada); Boston (USA) and UNICAMP (Brazil). Afterwards, I have been a postdoctoral fellow at the Universidad Autónoma de Barcelona and at the Centro de Investigaciones sobre América del Norte of the UNAM (Mexico).  Currently, I am Full Professor at the Department of Sociology and Social Anthropology of the University of Valencia. My research focused on various aspects of foreign immigration to Spain (demography, labor integration, specific groups, etc.), international emigration of Argentines and skilled migration. As a result of this work, I have written two dozen articles and chapters in collective books and an authored book. His teaching activity, however, extends to the sociology of work and education.
