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.

Carolyn Dacey Seib, MD, MAS
Associate Professor of Surgery (General Surgery)
BioDr. Carolyn Dacey Seib is a fellowship-trained endocrine surgeon and board-certified general surgeon who specializes in surgery of the thyroid, parathyroid, and adrenal glands. In 2025, she was among the first surgeons in the United States to earn a Focused Practice Designation in Complex Thyroid and Parathyroid Surgery from the American Board of Surgery, reflecting her expertise in these procedures and related patient management.
Dr. Seib provides comprehensive and personalized care for patients with thyroid, parathyroid, and adrenal disorders, including thyroid cancer, hyperthyroidism, primary hyperparathyroidism, primary aldosteronism, autonomous cortisol secretion, and pheochromocytomas. Her approach combines advanced surgical techniques with a focus on patient-centered outcomes, ensuring that each treatment plan is tailored to the individual.
In addition to her clinical practice, Dr. Seib is an NIH-funded researcher whose work focuses on optimizing surgical decision-making and outcomes for patients with endocrine disorders. She has received research support from the National Institute on Aging and the American Thyroid Association, and her studies have been published in leading peer-reviewed journals and featured in national media, including The New York Times.
Dr. Seib completed her undergraduate education at Princeton University (summa cum laude), earned her medical degree from the New York University School of Medicine, and completed her general surgery residency and endocrine surgery fellowship at the University of California, San Francisco (UCSF). -

Alicia Seiger
Affiliate, Bank of America
Visiting Scholar, Precourt Institute for EnergyBioAlicia Seiger is a recognized expert at the intersections of climate, technology, policy, finance, and innovation. She is a Visiting Scholar at SDSS and an occasional lecturer. Alicia currently directs the climate program at the Chan Zuckerberg Initiative (CZI). Prior to CZI, Alicia led sustainability and energy finance initiatives at Stanford Law, Graduate School of Business, and the Doerr School for Sustainability. Alicia has served as an advisor to the Governors of California and New York, the New York State Comptroller, and numerous pension fund, endowment, and family office CIOs on the topics of climate risk, opportunity, and resiliency. For over two decades, Alicia has designed and executed climate and energy strategies for businesses, foundations, investors, and NGOs. She has led on the management teams of multiple startups, including at TerraPass, a pioneer of the US voluntary carbon offset market, and Flycast Communications, one of the world’s first web advertising networks. She co-founded Stanford Professionals in Energy (SPIE) and serves on the boards of Prime Coalition and The E-liability Institute and on the Editorial Board of the Oxford Open Climate Change Journal.
Her first book, "Settling Climate Accounts: Navigating the Road to Net Zero" contextualizes the history of climate action, examines the practices of pursuing net zero, and makes recommendations for the road ahead. Alicia received her BA from Duke University in a self-designed curriculum intersecting environmental science and policy with cultural anthropology, and earned her MBA at the Stanford Graduate School of Business. -
Serdar Selamet
Adjunct Lecturer, Civil and Environmental Engineering
BioAssoc. Professor with focus on Fire Engineering, Steel Structures and Numerical Modeling. Dr. Selamet specializes in fire protection engineering with focus on buildings and structures. His areas of expertise include heat transfer analysis, stability and critical temperature assessment of structural members, passive fire protection, building envelope (i.e. façade) fires, performance-based structural analysis under fire conditions and house fires in wildland urban interface.

Elizabeth Selig, Ph.D.
Managing Director, Center for Ocean Solutions, Center for Ocean Solutions
BioElizabeth Selig works at the intersection of environmental and social sustainability in marine ecosystems. Her current research focuses on understanding social-ecological feedbacks in ocean health, marine resource conflicts, and patterns in illegal, unreported and unregulated fishing and labor abuses in fisheries. Selig received her Ph.D. in ecology at the University of North Carolina – Chapel Hill. Her dissertation focused on how global climate change may affect coral reef health and management strategies that can help mitigate coral loss. She has more than ten years of experience working with international non-governmental organizations including Conservation International, where she was the Senior Director of Marine Science. She has also worked at the Smithsonian Institution and the World Resources Institute.
