He also has been a Senior Fellow (by courtesy) at Stanford’s Freeman-Spogli Institute for International Studies, and a visiting fellow at the Hoover Institution. He founded the law school’s Environmental and Natural Resources Program. He also is a faculty member in Stanford’s Emmett Interdisciplinary Program in Environment and Resources (E-IPER).
Professor Thompson served as Special Master for the United States Supreme Court in Montana v. Wyoming, an interstate water dispute involving the Yellowstone River system. He also is a former member of the Science Advisory Board of the United States Environmental Protection Agency. He chairs the boards of the Resources Legacy Fund and the Stanford Habitat Conservation Board, is a California trustee of The Nature Conservancy, and is a board member of the American Farmland Trust, the Sonoran Institute, and the Santa Lucia Conservancy.
Professor Thompson is of counsel to the law firm of O’Melveny & Myers, where he specializes in water resources and was a partner prior to joining Stanford Law School. He also serves as an advisor to a major impact investment fund. He was a law clerk to Chief Justice William H. Rehnquist ’52 (BA ’48, MA ’48) of the U.S. Supreme Court and Judge Joseph T. Sneed of the U.S. Court of Appeals for the Ninth Circuit. -
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.

Edgar Virgüez
Research Engineer, Energy Science & Engineering
BioEdgar Virgüez is a Research Engineer in the Department of Energy Science & Engineering at Stanford University, where his work advances reliable, low-carbon energy systems. His findings have resulted in more than 40 scholarly outputs that have garnered over 950 citations in leading journals, including Energy & Environmental Science, Nature Cities, PNAS, and Science. Dr. Virgüez serves on the Editorial Board of Environmental Research: Energy. In 2026, he received the IOP Publishing Editorial Excellence Award, one of 10 awards granted to editorial board members selected from >1,000 members across the 100+ journals published by IOP. The recognition honors outstanding leadership and sustained excellence in peer review and editorial stewardship. Beyond his editorial board service, he actively contributes to peer review across 15 leading journals, including Nature Communications and Nature Sustainability.
Complementing his scholarship, Dr. Virgüez serves as Managing Director of the $23 million U.S. Department of Energy-funded EARNEST Consortium, led by Stanford University. This initiative brings together 18 universities, three national laboratories, and two research organizations to advance solutions for the future of the U.S. electricity system. Beyond EARNEST, he has collaborated with the World Bank and the Inter-American Development Bank, contributing expertise in life cycle assessment, cost-benefit analysis, and decarbonization strategies for governments and utilities across the Americas.
Globally, Dr. Virgüez contributes to major energy and climate initiatives. Since 2024, he has served as an Expert Advisor to the Earthshot Prize, founded by Prince William, reviewing nominations in the Fix Our Climate category and assessing their potential for innovation, impact, and scalability toward a $1.25 million annual award. He also serves in advisory roles for institutions such as Schmidt Sciences, evaluating research programs advancing scalable decarbonization and energy systems solutions, and provides expert review on energy-related reports for organizations, including the International Energy Agency.
For his contributions, Dr. Virgüez has received 22 awards totaling $34,365. Among his notable honors are the Science for Solutions Award (2025) from the American Geophysical Union, recognizing rising experts who have made significant contributions in the application and use of Earth and space science to solve societal problems, and the K. Patricia Cross Future Leaders Award (2020) from the Association of American Colleges and Universities, which recognizes rising scholars who demonstrate strong promise as future leaders in higher education. As an educator, Dr. Virgüez has taught 17 courses to ~600 students, with consistently outstanding evaluations. This achievement was recognized with the Graduate School Dean’s Award for Excellence in Teaching (2021) from Duke University.
In 2022, he was elected Young Trustee to the Board of Trustees of Duke University, the institution’s highest governing body, in recognition of his leadership and contributions to the university community, where he served a three-year term. He currently serves on Duke’s Climate Commitment Campaign Advocates Board, advising on the university’s philanthropic climate initiative, and will join the Advisory Board of the Nicholas School of the Environment (summer 2026).
Dr. Virgüez holds a Ph.D. in Environmental Sciences and Policy with a Certificate in College Teaching (2022) and an M.A. in Environment with a Geospatial Analysis Certificate (2018) from Duke University, along with an M.Sc. in Environmental Engineering (2010) and a dual B.Sc. in Chemical and Environmental Engineering (2009) from Universidad de los Andes. He has completed professional certificates in Australia, the United States, and Colombia, and has received more than $795,000 in competitive scholarships and fellowships sponsored by institutions including the Sloan Foundation. -

Madalina Vlasceanu
Assistant Professor of Environmental Social Sciences and, by courtesy, of Organizational Development at the Graduate School of Business
BioMadalina Vlasceanu is an Assistant Professor of Environmental Behavioral Sciences in the Department of Environmental Social Sciences at Stanford University’s Doerr School of Sustainability and the Director of the Climate Cognition Lab. Professor Vlasceanu is also a Faculty Fellow at the Stanford Center for Affective Science, the chair of the Society for Personality and Social Psychology at the United Nations, and a committee member of the Psychology Coalition at the United Nations, and the International Panel on the Information Environment. She obtained a PhD in Psychology and Neuroscience from Princeton University in 2021 and a BA in Psychology and Economics from the University of Rochester in 2016. Prior to Stanford, she was an Assistant Professor of Psychology at New York University. Her research focuses on the cognitive and social processes that give rise to emergent phenomena such as collective beliefs, collective decision-making, and collective action, with direct applications to climate policy. Guided by a theoretical framework of investigation, her research employs a large array of methods including behavioral laboratory experiments, social network analysis, field studies, randomized controlled trials, megastudies, and international many-lab collaborations, with the goal of understanding the processes underlying climate awareness and action at the individual, collective, and system level. Professor Vlasceanu's research is theoretically grounded and focused on applications for practice, incorporates an interdisciplinary perspective, and directly informs policies and practices relevant to climate mitigation and adaptation.

Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.
