BioCéline Scheidt has worked extensively in uncertainty modeling, sensitivity analysis, geostatistics and in the use of distance-based methods in reservoir modeling. She obtained her PhD at Strasbourg University and the IFP (France) in applied mathematics, with a focus on the use of experimental design and geostatistical methods to model response surfaces.

Allegra Hosford Scheirer is a research geophysicist at Stanford University, specializing in basin and petroleum system modeling. Her work is centered on the strong belief in the integration of geological, geochemical, and geophysical data in a unified working environment.
She co-teaches courses and co-advises several graduate students with a focus on basin and petroleum system modeling and investigative methods for exploring conventional and unconventional hydrocarbons.
Prior to joining Stanford, Allegra was a member of the Geophysical Unit of Menlo Park and the Energy Resources Program at the U.S. Geological Survey, where she constructed three-dimensional geologic models for use in the resource assessment process. Allegra has led and participated in numerous field programs at sea and in the United States. She is the editor of U.S.G.S. Professional Paper 1713 and a past Associate Editor of Journal of Geophysical Research.

BioI am interested in the fundamental problem of observing, understanding, and predicting the behavior of ice and water in the earth system. I am particularly interested in the role that subglacial water plays in the evolution and stability of continental ice sheets and their contribution to the rate of sea level rise. I am also interested in the development, use, and analysis of geophysical radar remote sensing systems that are optimized to observe hypothesis- specific phenomena. I consider myself an instrument scientist and seek to approach problems from both an earth system science and radar system engineering perspective. By focusing on the flow of information and uncertainty through the entire process of instrument development, experimental design, data processing, analysis, and interpretation, I can draw upon a multidisciplinary set of tools to test system-scale and process-level hypotheses. For me, this deliberate combination of science and engineering is the most powerful and satisfying way to approach questions in earth and planetary science.

I study active earthquake and volcanic process through data collection, inversion, and theoretical modeling. Using techniques such as the Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) my students and I 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. We use these results to develop and test models of active plate boundaries such as the San Andreas, and the Cascade subduction zone, the nucleation of earthquakes, slow slip events, and the physics of magma migration leading to volcanic eruptions.
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.

Current Research and Scholarly InterestsSamy researches how to estimate public opinion at state and local levels, so that public opinion data is more relevant for policymakers. She also studies how people form their attitudes toward climate change and how those attitudes shape behavior.
