    Associate Professor of Urology and, by courtesy, of Radiology (Body MRI)

    Current Research and Scholarly InterestsMy interest is in improving prostate cancer diagnosis through MRI and image-targeted prostate biopsy. In collaboration with radiologists at Stanford, we are working to define the optimal role of MRI in prostate cancer. We hope to improve cancer imaging to the point that some men with elevated PSA may safely avoid prostate biopsy. For those who need biopsy, we are evaluating novel MRI-US fusion targeted biopsy, a technique that greatly improves upon the conventional biopsy method.

  • Justin L. Sonnenburg

    Justin L. Sonnenburg

    Alex and Susie Algard Endowed Professor

    Current Research and Scholarly InterestsThe goals of the Sonnenburg Lab research program are to (i) elucidate the basic mechanisms that underlie dynamics within the gut microbiota and (ii) devise and implement strategies to prevent and treat disease in humans via the gut microbiota. We investigate the principles that govern gut microbial community function and interaction with the host using a broad range of experimental approaches including studies of microbiomes in diverse human cohorts.

    Current Research and Scholarly InterestsThe research interests in the Sperling Lab are Earth history and the evolution of life, and the interactions between the biosphere and the geosphere. As such this research can generally be considered paleontology, insofar as paleontology encompasses all aspects of the history of life.

    Consequently, we define our research agenda by the questions we are interested in, rather than the tools used. This research incorporates multiple lines of evidence, and multiple tools, to investigate questions in the history of life. These lines of evidence include fossil data, molecular phylogenetics, sedimentary geochemistry, and developmental and ecological data from modern organisms. Ultimately, the goal is to link environmental change with organismal and ecological response through the lens of physiology.

    Our field research takes place all over the world--current areas include:

    -NW Canada (Yukon and Northwest Territories): Research has been conducted on the early Neoproterozoic Fifteenmile Group, Cryogenian and Ediacaran Windermere Supergroup, and on the Ordovician-Devonian Road River Group in the southern Richardson Mountains
    -Southern Canadian Cordillera: Work here has focused on the early Cambrian Mural Formation and its soft-bodied fauna.
    -England and Wales: Cambrian-Silurian successions in the Welsh Basin
    -Namibia: Ediacaran Nama Group
    -Upwelling zones: We study the oxygen minimum zone offshore California as an analogue for ancient low-oxygen oceans.

  • Daniel Spielman

    Daniel Spielman

    Professor of Radiology (Radiological Sciences Lab) and, by courtesy, of Electrical Engineering

    Current Research and Scholarly InterestsMy research interests are in the field of medical imaging, particularly magnetic resonance imaging and in vivo spectroscopy. Current projects include MRI and MRS at high magnetic fields and metabolic imaging using hyperpolarized 13C-labeled MRS.

  • Alfred M. Spormann

    Alfred M. Spormann

    Professor of Civil and Environmental Engineering and of Chemical Engineering, Emeritus

    Current Research and Scholarly InterestsMetabolism of anaerobic microbes in diseases, bioenergy, and bioremediation

  • James Spudich

    James Spudich

    Douglass M. and Nola Leishman Professor of Cardiovascular Disease, Emeritus

    Current Research and Scholarly InterestsThe general research interest of this laboratory is the molecular basis of cell motility, with a current emphasis on power output by the human heart. We have three specific research interests, the molecular basis of energy transduction that leads to ATP-driven myosin movement on actin, the biochemical basis of the regulation of actin and myosin interaction and their assembly states, and the roles these proteins play in vivo, in cell movement, changes in cell shape and muscle contraction.

  • Randall Stafford

    Randall Stafford

    Professor of Medicine (Stanford Center for Research in Disease Prevention)

    Current Research and Scholarly InterestsAs Director of the SPRC Program on Prevention Outcomes and Practices, my work focuses on cardiovascular disease treatment and prevention, the adoption of new technology and practices, and patterns of physician practice, particularly medication prescribing. Specific interests include measuring and improving the quality of outpatient care, disparities in health care by race, gender, age and socioeconomic status, and interventions to improve prevention outcomes.
