Benjamin Shapero
Ph.D. Student in Earth System Science, admitted Autumn 2020
BioI am a geomicrobiologist and am broadly interested in the connections between protein biochemistry, environmental microbiology, and biogeochemistry. I hail from the surf town of Encinitas near San Diego. I completed my undergraduate studies at the University of Southern California (USC), where I majored in both Biological Sciences and Classical Saxophone Performance. At USC I volunteered in a cellular and molecular neuroscience lab, and it was there that I discovered my fascination with proteins. After graduation, I worked in a vaccine design lab at Scripps Research. This research fostered my growing fascination with protein biochemistry and further exposed me to the realm of microbiology. I have since followed my interests in proteins and microbiology, along with my longstanding passion for climate science, to the field of geomicrobiology. I am currently pursuing a Ph.D. in geomicrobiology at Stanford University in the Earth System Science department.

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. -
