Current Research and Scholarly InterestsAssessing the Health Impacts of the Major California Outages between 2017-2019
This research aims to investigate the relationship between major power outages and hospitalizations in California. Using outage data between 2017 and 2019, we are working to identify the hospitalization rates following outages. Additionally, we are evaluating how severe weather-caused outages can further impact hospitalizations. -
Larissa Verona
Ph.D. Student in Earth System Science, admitted Autumn 2026
BioI’m a PhD student in Earth System Science, advised by Prof. Alyson Hoyt. I’m interested in understanding the carbon dynamics of tropical wetlands by studying soils, isotopes, and gases, as well as landscape patterns through remote sensing. I earned a bachelor’s degree in biology and a master’s degree in plant biology from the Universidade Estadual de Campinas (Unicamp), Brazil, where I gained experience in functional and restoration ecology. More broadly, I’m curious about the functioning and conservation of tropical ecosystems, including non-forest ones such as savannas and grasslands.

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.

Katie Wu
Ph.D. Student in Environment and Resources, admitted Autumn 2022
Ph.D. Minor, Civil and Environmental EngineeringBioKatie's research explores how community-driven social interventions and infrastructure development impact community and climate resilience in informal settlements. Her work advances how we operationalize resilience to better inform community-based strategies, policy, and investments that support urban transformation for vulnerable populations. She incorporates participatory methods essential for driving community-led efforts, ensuring a community's deep participation in every step of the iterative analysis, planning, and decision-making processes, in collaboration with multi-sectoral partners and decision-makers. Katie integrates advanced data science techniques, including network science and graph neural networks (GNNs), with community-generated, ground-truthed data to redefine how resilience is measured and applied for more equitable, community-driven strategies for sustainable development. She uses unconventional data sources, such as satellite imagery and citizen-sourced data, to model the built and natural environment in areas with limited conventional data.
Prior to Stanford, Katie studied data science and AI for Product Innovation at Duke University, where she obtained a Master of Engineering Management (MEM). She was a Sustainability Graduate Intern at Lyft, Inc., where she completed and rebuilt their 2020 Greenhouse Gas (GHG) Inventory and Report and designed an air quality model forecasting potential health benefits of EV adoption for underserved communities. She received an M.S. in Medical Science from the University of Colorado School of Medicine and a B.S. in Animal Science with Distinction in Research from Cornell University. Katie is a Dean's Graduate Scholar in the Doerr School of Sustainability, an Emerson Consequential Scholar with the Stanford Technology Ventures Program (STVP), a Graduate Fellow at the Stanford Institute for Human-Centered AI (HAI), and a Stanford Dalai Lama Fellow. -
Flora Jiaxuan Xu
Ph.D. Student in Environment and Resources, admitted Autumn 2023
Ph.D. Minor, Psychology
Student Summer Research Assistant, Environmental Social SciencesBioFlora Jiaxuan Xu is a PhD candidate in the Emmett Interdisciplinary Program in Environment and Resources (E-IPER) at Stanford University, working at the intersection of environmental psychology, civil and environmental engineering, urban design, and behavioral science. Her research investigates how people define, experience, and internalize “nature” as part of the self, and how psychological, cultural, and built-environment factors shape human–nature relationships in contemporary cities.
Drawing on theories of identity, perception, cultural psychology, and ecological systems, Flora proposes Nature Identity as a new interdisciplinary framework for understanding how nature becomes woven into self-concept and everyday meaning-making. She employs a broad mixed-methods approach—including qualitative interviews, quantitative modeling, ecological momentary assessment, photovoice, and human-centered design—to examine how urban nature influences wellbeing, identity formation, and environmental behavior. In parallel, she develops creative, design-driven solutions such as immersive installations, biophilic illusions, narrative and sensory interventions, and technology-enabled building features that aim to strengthen nature connection and promote climate engagement in urban settings.
Flora works with the Social Ecology Lab and the Billington Lab, as well as external partners in urban design, behavioral science, and immersive storytelling. Her work seeks to bridge scientific research with real-world application, advancing strategies that integrate psychology, culture, and design to foster healthier and more nature-responsive cities.
Prior to Stanford, Flora completed an M.S. in Environmental Health at the Harvard T.H. Chan School of Public Health and holds B.A. degrees in Sustainable Environmental Design and Cognitive Science from the University of California, Berkeley. -
Ao Yu
Ph.D. Student in Earth System Science, admitted Autumn 2023
Masters Student in Earth System Science, admitted Autumn 2026BioAo Yu is a fourth-year Ph.D. candidate in Stanford University’s Department of Earth System Science. Working with Professor Giulio De Leo, she studies how anthropogenic disturbances, including climate change, pollution, and land-use change, affect the transmission of parasitic diseases.
Her current research focuses on schistosomiasis and Lyme disease. She combines laboratory experiments and fieldwork with geospatial analysis and mathematical and statistical modeling to investigate the ecological drivers of disease transmission. She also aims to translate these findings into practical, ecologically informed solutions for disease prevention and control.
Ao earned an M.P.H. in Environmental Health Sciences from the University of California, Berkeley, in 2023. She graduated with honors from Purdue University in 2021 with a B.S. in Biological Sciences and a minor in Chemistry. -
