  • Christine Jacobs-Wagner

    Christine Jacobs-Wagner

    Dennis Cunningham Professor, Professor of Biology and of Microbiology and Immunology

    BioChristine Jacobs-Wagner is a Dennis Cunningham Professor in the Department of Biology and the ChEM-H Institute at Stanford University. She is interested in understanding the fundamental mechanisms and principles by which cells, and, in particular, bacterial cells, are able to multiple. She received her PhD in Biochemistry in 1996 from the University of Liège, Belgium where she unraveled a molecular mechanism by which some bacterial pathogens sense and respond to antibiotics attack to achieve resistance. For this work, she received multiple awards including the 1997 GE & Science Prize for Young Life Scientists. During her postdoctoral work at Stanford Medical School, she demonstrated that bacteria can localize regulatory proteins to specific intracellular regions to control signal transduction and the cell cycle, uncovering a new, unsuspected level of bacterial regulation.

    She started her own lab at Yale University in 2001. Over the years, her group made major contributions in the emerging field of bacterial cell biology and provided key molecular insights into the temporal and spatial mechanisms involved in cell morphogenesis, cell polarization, chromosome segregation and cell cycle control. For her distinguished work, she received the Pew Scholars award from the Pew Charitable Trust, the Woman in Cell Biology Junior award from the American Society of Cell Biology and the Eli Lilly award from the American Society of Microbiology. She held the Maxine F. Singer and William H. Fleming professor chairs at Yale. She was elected to the Connecticut academy of Science, the American Academy of Microbiology and the National Academy of Sciences. She has been an investigator of the Howard Hughes Medical Institute since 2008.

    Her lab moved to Stanford in 2019. Current research examines the general principles and spatiotemporal mechanisms by which bacterial cells replicate, using Caulobacter crescentus and Escherichia coli as models. Recently, the Jacobs-Wagner lab expanded their interests to the Lyme disease agent Borrelia burgdorferi, revealing unsuspected ways by which this pathogen grows and causes disease

  • Tomas Jimenez

    Tomas Jimenez

    Professor of Sociology

    BioTomás Jiménez is Associate Professor of Sociology and Comparative Studies in Race and Ethnicity. He is also Director of the undergraduate program in Comparative Studies in Race and Ethnicity and Director of graduate studies in sociology. His research and writing focus on immigration, assimilation, social mobility, and ethnic and racial identity. His forthcoming 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. The book was awarded the American Sociological Association’s Sociology of Latinos/as Section Distinguished Book Award. Professor Jiménez has also published this research in the American Sociological Review, American Journal of Sociology, International Migration Review, Ethnic and Racial Studies, Social Science Quarterly, DuBois Review, and the Annual Review of Sociology.

    He is currently working several other projects. The first looks at how immigration becomes part of American national identity by studying a sample of high school US history textbooks from 1930-2005. A second project (with social psychologist John Dovidio (Yale), political scientist Deborah Schildkraut (Tufts), and social psychologist Yuen Ho (UCLA), uses survey data (with embedded experiments) and in-depth interviews to understand how state-level immigration policies 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 and the United Parcel Service Endowment Fund at Stanford. A third project (with graduate students Anna Boch and Katharina Roessler) uses Yelp! data to examine the contextual factors that predict whether Mexican food has entered a mainstream. In another project, Professor Jiménez, with Marrianne Cooper (Clayman Institute, Stanford University), and Chrystal Redekopp (Laboratory for Social Research, Stanford), are studying how Silicon Valley residents find alternative forms of housing in one of the most expensive real estate markets in the world.

    Professor Jiménez has taught at the University of California, San Diego. He has been named a 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 U.S. 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 he has written opinion-editorials on the topic of immigrant assimilation in several major news outlets, including the Los Angeles Times, CNN.com, The Chronicle of Higher Education, and the San Diego Union-Tribune.
