  • Aliya Saperstein

    Aliya Saperstein

    Benjamin Scott Crocker Professor of Human Biology

    BioProfessor Saperstein received her B.A. in Sociology from the University of Washington and her Ph.D. in Sociology and Demography from the University of California-Berkeley. In 2016, she received the Early Achievement Award from the Population Association of America. She has also been a Visiting Scholar at the Russell Sage Foundation and Sciences Po (Paris).

    Her research focuses on the social processes through which people come to perceive, name, and deploy seemingly immutable categorical differences —such as race and sex—and their consequences for explaining, and reinforcing, social inequality. Her current research projects explore several strands of this subject, including:

    1) The implications of methodological decisions, especially the measurement of race/ethnicity and sex/gender in surveys, for studies of stratification and health disparities.
    2) The relationship between individual-level category fluidity or ambiguity and the maintenance of group boundaries, racial stereotypes, and hierarchies.

    This research has been published for social science audiences in the American Journal of Sociology, the Annual Review of Sociology, Demography, Ethnic & Racial Studies, and Gender & Society, among other venues, and for general science audiences in the Proceedings of the National Academy of Sciences and PLoS One. It also has been recognized with multiple article awards, and gained attention from national media outlets, including NPR and The Colbert Report.

    Kavita Sarin, MD, PhD

    Professor of Dermatology

    Current Research and Scholarly InterestsMy research encompasses two main areas: 1) Using next-generation RNA, whole genome, and exome sequencing, we are investigating the genetic alterations involved in skin cancer progression, response to therapy, and other clinical outcomes and 2) We are developing and implementing genome-wide genetic risk prediction assessments for skin cancer into clinical use and studying the impact of this information on patient care.

  • Peter Sarnow

    Peter Sarnow

    Burt and Marion Avery Professor of Immunology

    Current Research and Scholarly InterestsOur laboratory studies virus-host interactions with an emphasis microRNA-mediated gene regulation and on translational control. The mechanism by which a liver-specific microRNA regulates hepatitis C virus genome replication is under intense scrutiny. In addition, the mechanism of internal ribosome entry in certain cellular and viral mRNAs and its biological role in growth and development is being investigated.

  • John Louis Sarrao

    John Louis Sarrao

    Director of the SLAC National Accelerator Laboratory, Professor of Photon Science, Senior Fellow at the Precourt Institute for Energy and Professor, by courtesy, of Materials Science and Engineering

    BioJohn Sarrao became SLAC National Accelerator Laboratory’s sixth director in October 2023. The lab’s ~2,000 staff advance the frontiers of science by exploring how the universe works at the biggest, smallest, and fastest scales and invent powerful tools used by scientists around the globe. SLAC’s research helps solve real-world problems and advances the interests of the nation. SLAC is operated by Stanford University for the U.S. Department of Energy’s Office of Science. It is home to three Office of Science national user facilities: the Linac Coherent Light Source (LCLS), the world’s most powerful X-ray laser; the Stanford Synchrotron Radiation Lightsource (SSRL); and the Facility for Advanced Accelerator Experimental Tests, (FACET-II). SLAC hosts thousands of users each year and manages an annual budget of ~$700M. In addition to his role as lab director, John is a professor of photon science, and by courtesy, of materials science and engineering at Stanford University, a senior fellow at Stanford’s Precourt Institute, and dean of SLAC faculty.

    John came to SLAC from Los Alamos National Laboratory (LANL) in New Mexico, where he served as the deputy director for science, technology, and engineering. In that role, he led multiple directorates, including chemistry, earth and life sciences, global security, physical sciences, and simulation and computation. He also stewarded technology transitions and served as LANL’s chief research officer in support of its national security mission. Before becoming deputy director, he served as associate director for theory, simulation, and computation and division leader for materials physics and applications at LANL.

    John’s scientific research focus is superconductivity in materials. He studies the synthesis and characterization of correlated electron systems, especially actinide materials. He won the 2013 Department of Energy’s E.O. Lawrence Award and is a fellow of the American Association for the Advancement of Science, the American Physical Society, and LANL. John received his PhD and master’s degree in physics from the University of California, Los Angeles, and a bachelor’s degree in physics from Stanford University.
