Flora Jiaxuan Xu
Ph.D. Student in Environment and Resources, admitted Autumn 2023
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. -

Da Yang
Assistant Professor Geophysics
Current Research and Scholarly InterestsMy research focuses on atmospheric convection and clouds—the major sources of uncertainty in predicting future climate change. Key questions in this field include: What makes air rise to form clouds? How do individual convective clouds organize into expansive rainstorms? How does convection work in warmer climates? I combine theory, observations, numerical models, and machine learning methods to address these most fundamental yet challenging questions.

Richard Zare
Marguerite Blake Wilbur Professor of Natural Science and Professor, by courtesy, of Physics
Current Research and Scholarly InterestsMy research group is exploring a variety of topics that range from the basic understanding of chemical reaction dynamics to the nature of the chemical contents of single cells.
Under thermal conditions nature seems to hide the details of how elementary reactions occur through a series of averages over reagent velocity, internal energy, impact parameter, and orientation. To discover the effects of these variables on reactivity, it is necessary to carry out studies of chemical reactions far from equilibrium in which the states of the reactants are more sharply restricted and can be varied in a controlled manner. My research group is attempting to meet this tough experimental challenge through a number of laser techniques that prepare reactants in specific quantum states and probe the quantum state distributions of the resulting products. It is our belief that such state-to-state information gives the deepest insight into the forces that operate in the breaking of old bonds and the making of new ones.
Space does not permit a full description of these projects, and I earnestly invite correspondence. The following examples are representative:
The simplest of all neutral bimolecular reactions is the exchange reaction H H2 -> H2 H. We are studying this system and various isotopic cousins using a tunable UV laser pulse to photodissociate HBr (DBr) and hence create fast H (D) atoms of known translational energy in the presence of H2 and/or D2 and using a laser multiphoton ionization time-of-flight mass spectrometer to detect the nascent molecular products in a quantum-state-specific manner by means of an imaging technique. It is expected that these product state distributions will provide a key test of the adequacy of various advanced theoretical schemes for modeling this reaction.
Analytical efforts involve the use of capillary zone electrophoresis, two-step laser desorption laser multiphoton ionization mass spectrometry, cavity ring-down spectroscopy, and Hadamard transform time-of-flight mass spectrometry. We believe these methods can revolutionize trace analysis, particularly of biomolecules in cells. -
Howard Zebker
Kwoh Ting Li Professor in the School of Engineering and Professor of Geophysics
Current Research and Scholarly InterestsResearch
My students and I study the surfaces of Earth and planets using radar remote sensing methods. Our specialization is interferometric radar, or InSAR. InSAR is a technique to measure mm-scale surface deformation at fine resolution over wide areas, and much of our work follows from applying this technique to the study of earthquakes, volcanoes, and human-induced subsidence. We also address global environmental problems by tracking the movement of ice in the polar regions. whose ice mass balance affects sea level rise and global climate. We participate in NASA space missions such as Cassini, in which we now are examining the largest moon of Saturn, Titan, to try and deduce its composition and evolution. Our work includes experimental observation and modeling the measurements to best understand processes affecting the Earth and solar system. We use data acquired by spaceborne satellites and by large, ground-based radar telescopes to support our research.
Teaching
I teach courses related to remote sensing methods and applications, and how these methods can be used to study the world around us. At the undergraduate level, these include introductory remote sensing uses of the full electromagnetic spectrum to characterize Earth and planetary surfaces and atmospheres, and methods of digital image processing. I also teach a freshman and sophomore seminar course on natural hazards. At the graduate level, the courses are more specialized, including the math and physics of two-dimensional imaging systems, plus detailed ourses on imaging radar systems for geophysical applications.

Weiwei Zhan
Postdoctoral Scholar, Earth System Science
BioI study the coupling between the global carbon and water cycles under climate change. Specifically, I investigate how plants regulate carbon uptake and water loss as atmospheric CO2 rises and water limitation intensifies, and how these responses feed back on the global environment. I develop hybrid physics–machine learning approaches and combine them with the expanding record of satellite and in situ observations to test hypotheses about ecosystem function.

Current Research and Scholarly InterestsResearch
I conduct research on in situ stress, fault mechanics, and reservoir geomechanics with an emphasis on shale gas, tight gas and tight oil production, the feasibility of long-term geologic storage of CO2 and the occurrence of induced and triggered earthquakes. I was one of the principal investigators of the SAFOD project in which a scientific research well was successfully drilled through the San Andreas Fault at seismogenic depth. I am the author of a textbook entitled Reservoir Geomechanics published in 2007 by Cambridge University Press, now in its sixth printing. I served on the National Academy of Energy committee investigating the Deepwater Horizon accident and the Secretary of Energy’s committee on shale gas development and environmental protection. I currently serve on a Canadian Council of Academies panel investigating the same topic.
