Paul Berne Burow
Postdoctoral Scholar, Earth System Science
BioI am a Postdoctoral Scholar in the Department of Earth System Science at Stanford University. I am an interdisciplinary social-environmental scientist studying how human communities are impacted by environmental change. My work examines the cultural dynamics of environmental change in North America across scales using mixed methods from ethnography and archival research to field ecology and spatial analysis. My postdoctoral project explores the social dimensions and institutional effectiveness of collaborative forest stewardship with federal agencies and Native Nations in California.
My previous work examined the social and cultural dimensions of environmental change in the North America's Great Basin. Based on thirty-six months of field-based ethnographic and historical research in California and Nevada, it investigated the cultural politics of land and its stewardship in dryland forest and shrub steppe ecosystems as it intersected with a changing climate, land use histories, and environmental governance regimes. Landscapes are undergoing material transformation due to climate change, land use practices, and colonialism, in turn reshaping how people relate to land, substantiate their place on it, and make claims to territory. This is creating new social-ecological configurations of people, land, and place I call ecologies of belonging, the subject of my current book manuscript.
Broadly, my research program addresses the sociocultural dimensions of climate and land use change, climate adaptation, and community-based land stewardship across North America. My areas of research and teaching interest include environmental anthropology, Indigenous environmental sciences/studies, ethnoecology, and human-environment geography. I am also engaged in community-based participatory research projects with Tribal Nations to expand Indigenous-led land stewardship and protect cultural landscapes from degradation for the benefit of future generations. -

Fa Li
Postdoctoral Scholar, Earth System Science
BioMy research investigates greenhouse gases emissions, wildfires/climate extremes, and nature-based solutions by combining data-driven approaches (e.g., physically interpretable AI and causality inference), process-based terrestrial biosphere/Earth system models, and big data (e.g., remote sensing, in-situ measurements).
For example, together with our collaborators at Stanford and beyond, I play a leading role in FLUXNET-CH₄ V2.0, a global network of methane tower measurements, to enhance the monitoring of methane emissions and support Global Carbon Project-Methane Budget.
