Sonia Tikoo-Schantz
Assistant Professor of Geophysics and, by courtesy, of Earth and Planetary Sciences
BioI utilize paleomagnetism and fundamental rock magnetism as tools to investigate problems in the planetary sciences. By studying the remanent magnetism recorded within rocks from differentiated planetary bodies, I can learn about core processes that facilitate the generation of dynamo magnetic fields within the Earth, Moon, and planetesimals. Determining the longevities and paleointensities of dynamo fields that initially magnetized rocks also provides insight into the long-term thermal evolution (i.e., effects of secular cooling) of planetary bodies. I also use paleomagnetism to understand impact cratering events, which are the most ubiquitous modifiers of planetary surfaces across the solar system. Impact events produce heat, shock, and sometimes hydrothermal systems that are all capable of resetting magnetization within impactites and target rocks via thermal, shock, and chemical processes. Therefore, I am able to use a combination of paleomagnetic and rock magnetic characterization to investigate shock pressures, temperatures, structural changes, and post-impact chemical alteration experienced by cratered planetary surfaces.

Adrian A. Wackett
Ph.D. Student in Geological Sciences, admitted Autumn 2022
BioAdrian A. Wackett was born and raised in Saint Paul, Minnesota (unceded Wahpekute/Dakota lands). He double majored in Chemistry and Geosciences at Trinity University (TX) before returning to Saint Paul and completing his MS degree in Land & Atmospheric Sciences (specifically pedology/biogeochemistry) at the University of Minnesota-Twin Cities, where he studied global w'o'rming. Before coming to Stanford as an NSF GRFP Fellow he traveled extensively through Latin America and SE Asia (by bike) and worked as an independent researcher affiliated with the Department of Ecology and Environmental Sciences at Umeå University and the Climate Impacts Research Centre in Abisko, Sweden. He's passionate about exploring the interconnectedness of Earth’s systems through his research and is equally passionate about looking beyond academia to cultivate enduring relationships with the lands and peoples he works with.Previous topics of inquiry include coupling ant bioturbation to the erosion and weathering of hillslope soils in SE Australia, exploring earthworm invasions and their deterministic effects on soil carbon dynamics in Fennoscandian and Alaskan forests, and examining the biogeochemical diversity of ‘black smoker’ plume particles at deep-sea hydrothermal vents. His dissertation focuses on applying an array of isotopic tracers and synchrotron-based X-ray approaches to explore how landscapes record and respond to a diverse set of disturbances, from biological invasions in Earth’s northern biomes to extreme storm events in Puerto Rico to cultural burning and wildfires in California.

Jane Kathryn Willenbring
Associate Professor of Earth and Planetary Sciences and, by courtesy of Earth System Science
BioJane Willenbring joined Stanford as an Associate Professor in the summer of 2020. Jane is a geologist who solves problems related to the Earth surface. Her research is primarily done to understand the evolution of the Earth’s surface - especially how landscapes are affected by tectonics, climate change, and life. She and her research group use geochemical techniques, high-resolution topographic data, field observations, and, when possible, couple these data to landscape evolution numerical models and ice sheet models. The geochemical tools she uses and develops often include cosmogenic nuclide systems, which provide powerful, novel methods to constrain rates of erosion and mineral weathering. Jane has also started to organize citizen science campaigns and apply basic science principles to problems of human health with an ultimate broader impact goal of cleaning up urban areas and environments impacted by agriculture. She received her B.Sc. with honors from the North Dakota State University where she was a McNair Scholar and in the NDSU scholars program. She holds a Masters degree from Boston University. Her Ph.D. is in Earth Science from Dalhousie University in Halifax, Nova Scotia Canada where she was a Killam Scholar. She was a Synthesis Postdoctoral Fellow through the National Center for Earth Surface Dynamics at the Saint Anthony Falls Lab at the University of Minnesota, and an Alexander von Humboldt Postdoctoral Fellow and then subsequently a Postdoctoral Researcher at the Helmholz GFZ Potsdam, Germany. Jane was previously an Associate Professor in the Geosciences Research Division and Thomas and Evelyn Page Chancellor's Endowed Faculty Fellow at Scripps Institution of Oceanography, UC San Diego where she was the director of the Scripps Cosmogenic Isotope Laboratory (SCI-Lab). She was also a tenure-track professor at the University of Pennsylvania. She will be a Stanford University Gabilan Faculty Fellow in 2021-2023. She is a Fellow of the Geological Society of America and was the inaugural recipient of the Marguerite T. Williams award from the American Geophysical Union.
