Daniel Jarosz
Associate Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly InterestsMy laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.

Hakeem Jefferson
Assistant Professor of Political Science
BioI am an assistant professor of political science at Stanford University where I am also a faculty affiliate with the Center for Comparative Studies in Race and Ethnicity and the Stanford Center for American Democracy. I received my PhD in political science from the University of Michigan and a Bachelor of Arts degree in political science and African American Studies from the University of South Carolina.
My research focuses primarily on the role identity plays in structuring political attitudes and behaviors in the U.S. I am especially interested in understanding how stigma shapes the politics of Black Americans, particularly as it relates to group members’ support for racialized punitive social policies. In other research projects, I examine the psychological and social roots of the racial divide in Americans’ reactions to officer-involved shootings and work to evaluate the meaningfulness of key political concepts, like ideological identification, among Black Americans.
My dissertation, "Policing Norms: Punishment and the Politics of Respectability Among Black Americans," was a co-winner of the 2020 Best Dissertation Award from the Political Psychology Section of the American Political Science Association. -

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.
