Tomás R. Jiménez
Joan B. Ford Professor
BioTomás Jiménez is the Joan B. Ford Professor in the department of Sociology and Comparative Studies in Race and Ethnicity, and founding co-director of Stanford's Institute for Advancing Just Societies. He is also the director of the Qualitative Initiative in the Immigration Policy Lab. His research and writing focus on immigration, policy, assimilation, social mobility, and ethnic and racial identity. His latest book, States of Belonging: Immigration Policies, Attitudes, and Inclusion (Russell Sage Foundation Press) (with Deborah Schildkraut, Yuen Ho, and John Dovidio) uses survey data (with an embedded experiment) and in-depth interviews to understand how state-level immigration policies shape belonging among Latino immigrants, US-born Latinos, and US-born whites in Arizona and New Mexico. The American Sociological Association’s Population Section selected the book for its Otis Dudley Duncan Distinguished Book Award. His second book, The Other Side of Assimilation: How Immigrants are Changing American Life (University of California Press, 2017), uses interviews from a race and class spectrum of Silicon Valley residents to show how a relational form of assimilation changes both newcomers (immigrants and their children) and established individuals (people born in the US to US-born parents). His first book, Replenished Ethnicity: Mexican Americans, Immigration, and Identity(University of California Press, 2010), draws on interviews and participant observation to understand how uninterrupted Mexican immigration influences the ethnic identity of later-generation Mexican Americans. Professor Jiménez has also published his research in Science, American Sociological Review, American Journal of Sociology, American Political Science Review, Proceedings of the National Academy of Sciences, Social Problems, International Migration Review, Ethnic and Racial Studies, Social Science Quarterly, DuBois Review, Social Currents, Qualitative Sociology, and the Annual Review of Sociology.
Professor Jiménez also researches immigration policy with Stanford's Immigration Policy Lab, directing the Lab's Qualitative Initiative to integrate qualitative and quantitative approaches in research to have policy impact. Current projects examine naturalization, refugee resettlement (with Pei Palmgren), and health and language access.
In other lines of research, Professor Jiménez and Sofia Avila examine how immigration becomes part of American national identity by studying a sample of high school US history textbooks from 1930-2007. This research employs hand-coding and computer-assisted text analysis of the textbook sample.
Professor Jiménez has taught at the University of California, San Diego. He was the Sigma Xi Distinguished Lecturer (2017-19). He has also been an Irvine Fellow at the New America Foundation and a Sage Fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford University (CASBS). He was the American Sociological Association Congressional Fellow in the office of US Rep. Michael Honda, where he served as a legislative aide for immigration, veterans’ affairs, housing, and election reform. His writing on policy has appeared in reports for the Immigration Policy Center and the Migration Policy Institute. He has written editorials on immigration in several major news outlets, including The Washington Post, Los Angeles Times, CNN.com, The Chronicle of Higher Education, The Hill, and the San Diego Union-Tribune. He has also offered commentary for media outlets, including NBC News, National Public Radio, and Univision. -

Esther M. John
Professor (Research) of Epidemiology and Population Health and of Medicine (Oncology)
Current Research and Scholarly InterestsDr. John has extensive expertise in conducting population-based epidemiologic studies and has led as Principal Investigator multiple large-scale studies, including multi-center studies with a study site in the San Francisco Bay Area with its diverse population. Many of her studies and collaborations investigated cancer health disparities. Her research has focused on the role of modifiable lifestyle factors (e.g., body size, physical activity, diet), hormonal factors, early-life exposures, genetic variants, and gene-environment interactions; differences in risk factors by race and ethnicity, breast cancer subtypes, and prostate cancer subtypes; risk factors for familial breast cancer and second primary breast cancer, as well as prognostic factors related to survival disparities.
As Principal Investigator, Dr. John has led a number of studies conducted in the San Francisco Bay Area, including:
- the Northern California site of the Breast Cancer Family Registry, an on-going prospective multi-generational cohort of over 13,000 families established in 1995 at six international sites;
- the San Francisco Bay Area Breast Cancer Study, a population-based case-control study in nearly 5,000 African American, Hispanic, and non-Hispanic White women that investigated the role of modifiable lifestyle factors and other risk factors;
- the California site of the Breast Cancer Health Disparities Study that investigated genetic variability and breast cancer risk and survival in Hispanic and non-Hispanic White populations in the context of genetic admixture;
- the Breast Cancer Etiology in Minorities (BEM) Study, a pooled analysis of risk factors for breast cancer subtypes in minoritized racial and ethnic populations;
- the Northern California site of the WECARE Study that investigates risk factors for second primary contralateral breast cancer;
- the Second Primary Breast Cancer Disparities Study, a pooled analysis of risk factors for contralateral and ipsilateral second primary breast cancer in a diverse population;
- the San Francisco Bay Area Prostate Cancer Study, a population-based case-control study of lifestyle and genetic risk factors for advanced and localized disease.
These studies collected and pooled extensive data and biospecimens and continue to support numerous ancillary studies, collaborations and international consortia and have contributed to a better understanding of cancer risk and survival in minoritized racial and ethnic populations.
Dr. John is a founding PI of the LEGACY Girls Study, a prospective cohort established in 2011 that investigates early life exposures in relation to pubertal development outcomes, breast tissue characteristics, and behavioral and psychosocial outcomes in the context of having a family history or breast cancer.
In 2023, Dr. John joined the Stanford investigator team of the MOSAAIC (The Multiethnic Observational Study in American Asian and Pacific Islander Communities) Study, a five-center study to improve health of American Asian, Native Hawaiian, and Pacific Islander populations. -
