Eva L. Scheller
Assistant Professor of Earth and Planetary Sciences
Current Research and Scholarly InterestsPlanetary surface chemistry of terrestrial and icy worlds
What are the chemical inventories across the surfaces of solid planetary bodies? How were primary surface chemistry trends created through processes governing solid body planetary evolution? To what extent is in-situ characterized planetary surface chemistry (ices, volatiles, salts, aqueous minerals, organic compounds) tracers of ancient planet-shaping reactions, environmental and physical conditions, and geological processes?
Long-term planetary volatile evolution
How do geochemical reactions between terrestrial body atmospheres, surfaces, crust, and interiors affect the evolution of Mars and Venus’ atmospheres and habitable surface environments over geological time? What are the major inventories of volatiles on terrestrial and icy worlds, how do they change, and how are they lost/retained over time?
Numerical, probabilistic, and autonomous methods for planetary chemistry
How can we infer material compositions and chemical processes while rigorously quantifying uncertainty and ambiguity in sparse planetary datasets? How can laboratory measurements, physical models, and spacecraft observations be combined into coherent chemical interpretations? How can we develop trustworthy autonomous methods that rigorously maximizes chemical information yield from spacecraft missions and minimizes human bias?
Spaceflight instrumentation for planetary chemical analysis
How can planetary missions make reliable and quantified chemical discoveries with limited measurements and incomplete prior knowledge? How can instruments detect trace compounds and distinguish genuine chemical signatures from contamination, instrumental artifacts, and degenerate signals? How can we maximize chemical information within engineering and mission constraints? Can scientific output of planetary missions be optimized reliably through intelligent instrumentation and autonomous decision-making? -
Dustin Schroeder
Professor of Geophysics, of Electrical Engineering and Senior Fellow at the Woods Institute for the Environment
BioDustin Schroeder is a Professor of Geophysics and of Electrical Engineering at Stanford University. His research primarily focuses on observing and understanding the role of continental ice sheets and their contribution to the rate of sea level rise. A growing secondary focus of his work is the subsurface exploration of icy worlds. He also works on the development, use, and analysis of geophysical radar systems optimized to observe hypothesis-specific phenomena.
He serves on the Science Team for the REASON radar instrument on NASA’s Europa Clipper mission and previously co-chaired the mission’s Interior Working Group. At Stanford, he serves as Associate Chair of Geophysics, Associate Chair for Undergraduate Education in Electrical Engineering, Faculty Director for COLLEGE 102: Citizenship in the 21st Century, part of Stanford’s new first-year core curriculum, and Chair of the Faculty Senate. Beyond Stanford, he serves as Vice President of the International Glaciological Society and has served for more than two decades with the National Science Olympiad, including as chair of its national Earth and Space Sciences committee and as a member of its Executive Board.
Schroeder is a Fellow of the American Geophysical Union and a Senior Member of IEEE, and is a recipient of the AGU James B. Macelwane Medal and the National Science Foundation CAREER Award. His teaching has been recognized with awards across Stanford and through his selection as a Bass University Fellow in Undergraduate Education.
Before joining Stanford, he was a Radar Systems Engineer at NASA’s Jet Propulsion Laboratory at the California Institute of Technology. He earned his PhD in Geophysics from the University of Texas at Austin and holds a BS in Electrical Engineering and a BA in Physics from Bucknell University. Between his undergraduate and graduate studies, he worked as a Platform Hardware Engineer at Freescale Semiconductor. -
Krish Seetah
Associate Professor of Environmental Social Sciences, of Oceans, of Anthropology and Senior Fellow at the Woods Institute for the Environment
BioI am a zooarchaeologist, whose focus is primarily on colonisation and colonialism. My zooarchaeological research has used butchery analysis (with the benefit of professional and ethnographic actualistic experience) to investigate agency within the human-animal relationship. More recently, I have employed geometric morphometrics (GMM) as a mechanism for identifying and distinguishing animal populations. This approach to studying colonial activity centres on understanding how people manipulate animal bodies, both during life and after death.
Alongside the strictly faunal research is a research interest in technologies associated with animal processing. This has been used to investigate issues of technology, trade and socio-economic attitudes within colonial contexts in the Mediterranean (Venice & Montenegro) and the Baltic (Poland, Latvia & Lithuania).
I am also the Director of the ‘Mauritian Archaeology and Cultural Heritage’ (MACH) project, which studies European Imperialism and colonial activity. This project centres on the movement of peoples and material cultures, specifically within the contexts of slavery and Diaspora. The work of this project has focused on key sites in Mauritius and is based on a systematic programme of excavation and environmental sampling. The underlying aims are to better understand the transition from slavery to indentured labour following abolition, the extent and diversity of trade in the region and the environmental consequences of intense, monoculture, agriculture. -

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.
