Tomas Jimenez’s ’98’s book, Replenished Ethnicity: Mexican Americans, Immigration, and identity (University of California Press, 2010) was recently awarded the American Sociological Association’s Sociology of Latinos/as Section 2011 Distinguished Book Award. Professor Jiménez has also published this research in the American Journal of Sociology, Ethnic and Racial Studies, Social Science Quarterly, DuBois Review, and the Annual Review of Sociology. He is currently working on three projects. (1) The first—which is funded by grants from the National Science Foundation, the Stanford United Parcel Service Endowment Fund, and the Stanford Institute for Research in the Social Sciences—examines how host-society individuals (U.S.-born of U.S.-born parents) participate in the assimilation process by drawing on in-depth interviews with host-society individuals and observations in three distinct sub-regions in the Silicon Valley: East Palo Alto, Cupertino, and Berryessa. (2) A second project (with Stanford PhD Candidate, Lorena Castro) looks at how immigration becomes part of American national identity by studying a sample of high school US history textbooks from 1930-2005. (3) A third project—with social psychologist John Dovidio (Yale), political scientist Deborah Schildkraut (Tufts), and social psychologist Yuen Ho (UCLA)—uses lab experiments, survey data, and in-depth interviews to understand how contextual factors shape the sense of belonging and related intergroup attitudes, behaviors, and support for immigration policies among immigrants and host-society members in the United States. This project is funded by the Russell Sage Foundation.
