Paul Segall
The Cecil H. and Ida M. Green Professor of Geophysics
Current Research and Scholarly InterestsResearch
I study active earthquake and volcanic process through data collection, inversion, and theoretical modeling. Using methods such as precise Global Positioning System (GPS) positioning and Interferometric Synthetic Aperture Radar (InSAR) we are able to measure deformation in space and time and invert these data for the geometry of faults and magma chambers, and spatiotemporal variations in fault slip-rate and magma chamber dilation. The accumulation of shear strain in tectonic regions provides a direct measure of earthquake potential. Similarly, magma accumulation in the crust prior to eruptions causes measurable inflation. We use these data to develop and test models of active plate boundaries such as the San Andreas, and the Cascade and Japanese subduction zones, the nucleation of earthquakes, slow slip events, induced seismicity, and the physics of magma migration leading to volcanic eruptions. These physics-based models rely on principles and methodologies from solid and fluid dynamics.
Teaching
I teach introductory undergraduate classes in natural hazards and the prediction of volcanic eruptions, as well as graduate level courses on modeling earthquake and volcano deformation and geophysical inverse theory.

Deborah Sellmeyer
Clinical Professor, Medicine - Endocrinology, Gerontology, & Metabolism
BioDr. Sellmeyer is an internationally recognized expert in Metabolic Bone Disease. She is a renowned clinician who joined the Stanford faculty in 2018 as a Professor of Medicine. She has been recognized for her clinical excellence with induction into the Miller Coulson Academy of Clinical Excellence while she was at Johns Hopkins. In addition to her clinical expertise, Dr. Sellmeyer maintains a research program that centers on the effect of nutrition and environmental factors on skeletal metabolism which she has investigated through both smaller CRC-based trials and large multi-center trials. Studies she has conducted have investigated the role of dietary sodium chloride, source of dietary protein (animal, vegetable, dairy, soy), role of dietary potassium and alkaline potassium salts, targeted thoracic exercises on kyphosis, whether structured exercise can prevent bone loss in premenopausal women treated for breast cancer, and studies validating nutritional assessment questionnaires. Her expertise as a clinical researcher has enabled development of a multi-disciplinary translational research team including basic scientists in the orthopedic department, junior faculty members with K grant funding, and basic scientists in the endocrine division to develop translational projects studying the effects of osteoporosis medications on basic elements of skeletal biology utilizing bone biopsies from treated individuals as well as clinical trials of novel therapies for rare bone disorders. Dr. Sellmeyer also is a esteemed educator, having received multiple teaching awards.
