Ayla Pamukcu
Assistant Professor of Earth and Planetary Sciences
Current Research and Scholarly InterestsI have long been fascinated by magmas and volcanic eruptions, for reasons ranging from purely academic (trying to understand the magmatic construction of Earth’s crust) to purely practical (developing effective monitoring and mitigation strategies for volcanic eruptions). Consequently, my research revolves around understanding how, when, where, and why magmas are stored, evolve, and ultimately do (or do not!) erupt.
Within this context, I focus on two main themes: (1) the temporal, chemical, and physical, evolution of magmas, and (2) the interplay between magma storage conditions in the crust and magmatic processes. I employ a multi-faceted approach to explore these topics, integrating data from multiple scales and perspectives; my studies capitalize on information contained in field relations, crystal and melt inclusion textures (sizes, shapes, positions), crystal and volcanic glass geochemistry, geochronology, phase-equilibria and numerical modeling, and experiments. As a function of this approach, I am also engaged in the development of novel methods to address petrologic problems in new, better, and more refined ways than is currently possible.
A major focus of my research has been on supereruptions – gigantic explosive eruptions the likes of which we have never seen in recorded human history – but I am continually exploring other kinds of magmatic systems. I am currently particularly interested in the links (or lack thereof) between extrusive (i.e., erupted) and intrusive (i.e., unerupted) magmas, similarities/differences between large- and small-volume eruptions, and similarities/differences between magmas generated at different levels of the crust. I have also had a longstanding interest in the interactions and relationships between humans and their geologic surroundings (particularly volcanoes). -
Nidhi Utkarshbhai Patel
Ph.D. Student in Earth and Planetary Sciences, admitted Autumn 2023
BioPlants display enormous diversity of forms today that, have evolved over geological timescales after plants successfully colonized land. Currently, I am interested in learning more about evolutionary changes in plant structures including specialized reproductive organs of seed plants. I study plant fossil record from deep time and living plants with the aim to develop a better understanding of origins of plant reproductive structures and drivers of morphological evolution in plants. Previously, I have looked at spore-pollen record preserved in sedimentary rocks from Canada. These microscopic fossils and their distribution in space and time can help us elucidate the response of vegetation to past extinction events.

Eliane Petersohn
Ph.D. Student in Geological Sciences, admitted Autumn 2022
BioI grew up in Curitiba, a city in southern Brazil, and, moved to Rio de Janeiro to join the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) years ago.
I have a strong grasp of the oil and gas industry, where I have been working for more than 15 years. I have a bachelor’s and master's degree in geology from the Federal University of Parana, Brazil and, I have become a public servant of the ANP, where I have held different technical and managerial positions. I spent these past 15 years working on the ANP’s large-scale strategic projects, conducting a geological evaluation for Brazil’s bidding rounds, and developing a multiyear geological and geophysical data acquisition plan for the Agency. I was also responsible for coordinating the first phase of the onerous assignment process, which authorized the Brazilian Government to onerously assign to NOC Petrobras up to 5 billion barrels of oil. I have also been directly involved in the location of two wells, which discovered two of the country's largest oil fields (Buzios and Mero fields). As a geologist researcher, my main objective aims at acquiring capabilities and developing the knowledge required to manage reservoirs to maximize oil recovery and extend the lifespan of oil fields as well as acquire a solid understanding of oil reservoir management to bring innovative knowledge to Brazil and help create guidelines to monitor oil field development and production in my country. -

Erik Sperling
Associate Professor of Earth and Planetary Sciences, Senior Fellow at the Woods Institute for the Environment and Associate Professor, by courtesy, of Oceans
Current Research and Scholarly InterestsThe research interests in the Sperling Lab are Earth history and the evolution of life, and the interactions between the biosphere and the geosphere. As such this research can generally be considered paleontology, insofar as paleontology encompasses all aspects of the history of life.
Consequently, we define our research agenda by the questions we are interested in, rather than the tools used. This research incorporates multiple lines of evidence, and multiple tools, to investigate questions in the history of life. These lines of evidence include fossil data, molecular phylogenetics, sedimentary geochemistry, and developmental and ecological data from modern organisms. Ultimately, the goal is to link environmental change with organismal and ecological response through the lens of physiology.
Our field research takes place all over the world--current areas include:
-NW Canada (Yukon and Northwest Territories): Research has been conducted on the early Neoproterozoic Fifteenmile Group, Cryogenian and Ediacaran Windermere Supergroup, and on the Ordovician-Devonian Road River Group in the southern Richardson Mountains
-Southern Canadian Cordillera: Work here has focused on the early Cambrian Mural Formation and its soft-bodied fauna.
-England and Wales: Cambrian-Silurian successions in the Welsh Basin
-Namibia: Ediacaran Nama Group
-Upwelling zones: We study the oxygen minimum zone offshore California as an analogue for ancient low-oxygen oceans. -

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.

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.
