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).

Member, Bio-X
Current Research and Scholarly InterestsHow are genes regulated to construct a developmental program? How do signals received from other cells change the program and coordinate it for multicellular development? The approach taken by our laboratory group to answer these questions utilizes biochemistry and genetics; genetics to isolate mutants that have particular defects in development and biochemistry to determine the molecular basis of the defects. We study swarming in Myxococcus xanthus that builds fruiting bodies.

Agnieszka Kalinowski
Clinical Assistant Professor, Psychiatry and Behavioral Sciences
BioI am a translational physician-scientist committed to understanding the pathophysiology of schizophrenia to identify disease-modifying therapeutic interventions. I examined the role of C4 protein activation in clinical samples from individuals with schizophrenia compared to controls, its relationship to C4 CNV and effect on blood brain barrier permeability using in vitro model systems. I contributed to identifying LINE-1 insertions in postmortem brain samples of individuals with schizophrenia and C4 copy number variation (CNV) in pediatric patients with neuropsychiatric symptoms. Since accumulating evidence points to the synapses as the locus of pathology in schizophrenia, I am focusing my current research effort to defining the underlying abnormality in synapses in schizophrenia using a combination of in vitro iPS based model systems and postmortem brain samples, and applying cutting-edge techniques like spatial transcriptomics and array tomography.

Renata Kallosh
Stanford W. Ascherman, MD Professor, Emerita
BioWhat is the mathematical structure of supergravity/string theory and its relation to cosmology?
Professor Kallosh works on the general structure of supergravity and string theory and their applications to cosmology. Her main interests are related to the models early universe inflation and dark energy in string theory. She develops string theory models explaining the origin of the universe and its current acceleration. With her collaborators, she has recently constructed de Sitter supergravity, which is most suitable for studies of inflation and dark energy and spontaneously broken supersymmetry.
She is analyzing possible consequences of the expected new data from current and future cosmological observations, including LiteBIRD satellite CMB data. These results may affect the relationship between superstring theory and supergravity, and the real world. Professor Kallosh works, in particular, on future tests of string theory by CMB data and effective supergravity models with flexible amplitude of gravitational waves produced during inflation. -
