Assistant Professor of Medicine (Infectious Diseases) and of Microbiology and Immunology
BioI am an Infectious Diseases specialist with a research program in human immunology focused on malaria-specific immune responses in pregnancy and infancy. My current research program is to further our understanding of the mechanisms of clinical immunity to malaria through field-based studies, and to better understand the immunologic consequences of malaria control interventions.
Given the profound global impact of the COVID-19 pandemic, we are also testing novel immune modulating therapeutics for the treatment of SARS-CoV-2 infected patients with mild infection (NCT 04331899). In this study 120 SARS-CoV-2 infected patients (both symptomatic and asymptomatic) are being randomized to receive Lambda vs. placebo to test the hypothesis that SARS-CoV-2-infected individuals given Lambda at the time of diagnosis have a shortened duration of viral shedding in comparison to patients given placebo. I serve as as the co-PI of this study along with Dr. Upi Singh at Stanford.
Assistant Professor of Pathology
Current Research and Scholarly InterestsWe identified a common disorder of aging called clonal hematopoiesis of indeterminate potential (CHIP). CHIP occurs due to certain somatic mutations in blood stem cells and represents a precursor state for blood cancer, but is also associated with increased risk of cardiovascular disease and death. We hope to understand more about the biology and clinical implications of CHIP using human and model system studies.

Assistant Professor of Genetics
BioLivnat Jerby is an Assistant Professor of Genetics at Stanford University. Her research focuses on multicellular dynamics, as a disease driver and therapeutic avenue, particularly in the context of cancer immunology. In her work, she aims to identify the drivers, molecular underpinnings, and causal structure of multifactorial immune evasion mechanisms, and use this information to identify new and more effective ways to augment and unleash targeted immunity via combinatorial interventions. To address this challenge at scale, she develops integrative approaches, fusing single-cell sequencing and imaging with machine learning, genetic and environmental perturbations.
Thus far, her research provided new perspectives to key facets of tumor biology, encompassing metabolism, genetics, and immunology. As a postdoctoral fellow in Aviv Regev's lab at the Broad Institute of MIT and Harvard, she identified regulators of T cell exclusion and dysfunction. She holds a B.Sc. in Computer Science and Biology and obtained her PhD in 2016 from Tel Aviv University, where she worked with Eytan Ruppin and developed new ways to interrogate cancer metabolism and genetics.
This fall Livnat joined Stanford Genetics to establish a multidisciplinary lab that will harness machine learning in combination with clinical data and extensive functional testing to dissect and target immune dysregulation in cancer, aiming to leverage the versatile, interconnected function of genes, cells, and tissues for disease detection, prevention, and treatment.
Her research has been generously supported by the Schmidt Family Foundation, Rothschild Foundation, the Cancer Research Institute (CRI), the Burroughs Wellcome Fund (BWF), Ovarian Cancer Research Alliance (OCRA), Paul G.

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.

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/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 Northern California site of the WECARE Study that investigates risk factors for second primary breast cancer;
- 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 racial/ethnic minorities;
- the San Francisco Bay Area Breast Cancer Study, a population-based case-control study in nearly 5,000 Hispanic, African American and non-Hispanic white women that investigated the role of modifiable lifestyle factors and other risk factors;
- 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 racial/ethnic minority populations.
Dr. John is also a founding PI of the LEGACY Girls Study, an on-going 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.
