Alireza Namayandeh
Postdoctoral Scholar, Earth System Science
Current Research and Scholarly InterestsAlireza Namayandeh’s research focuses on the formation, transformation, and environmental impacts of metal-bearing nanoparticles in soil, water, and air, with a particular emphasis on their role in wildfire-generated pollution. His work investigates how wildfires contribute to the release and transport of toxic metal nanoparticles, assessing their chemical and physical properties and their implications for human health and ecosystem contamination.
His current research, supported by the NSF Earth Science Postdoctoral Fellowship, explores the mechanisms by which biomass burning generates toxic airborne nanoparticles and how soil mineralogy influences their formation. By combining laboratory experiments, synchrotron-based spectroscopy, electron microscopy, and field studies, he aims to better understand the pathways of metal mobilization during wildfires. He is also leading efforts to analyze ash and soil samples from recent wildfires in California, including the Eaton and Palisade fires in Los Angeles, to assess the risks associated with airborne metal nanoparticles.
Beyond wildfire-driven pollution, he is interested in the fundamental geochemistry of nanoparticle formation and transport. His previous work on precursor clusters of iron oxy-hydroxides provided new insights into the formation of metal-bearing nanoparticles and their role in controlling contaminant mobility in the environment. He continues to explore how ultrafine particles interact with toxic metals, organic matter, and microbial communities in both terrestrial and atmospheric systems.
His broader scholarly interests include wildfire geochemistry, atmospheric particulate matter, environmental mineralogy, and the intersection of environmental geochemistry and public health. His goal is to develop a deeper understanding of how natural and anthropogenic processes influence the formation and dispersion of hazardous nanoparticles, ultimately contributing to improved air quality standards, risk assessment models, and environmental policies in wildfire-prone regions. -

Ryan OConnor
Postdoctoral Scholar, Environmental Social Sciences
BioRyan O’Connor is an Environmental Social Scientist and current Postdoctoral Scholar in the Environmental Social Sciences Department at Stanford University. Ryan’s research focuses broadly on understanding the Human Dimensions of Environmental Governance and how human societies interact with, learn about, and manage social-ecological systems. His research employs an innovative blend of quantitative and qualitative social-ecological methods to elevate and highlight community voices and local ecological knowledge in conservation and to investigate how communities learn about and act upon convergence crises of climate change, biodiversity loss, and social-ecological resilience. By understanding how a person's relationship to the nature-rich world, personal history with nature, and social context shape individual perceptions of the environment management, Ryan seeks to inform the co-production of sustainable governance programs. Ryan also teaches courses on research methods, human-nature interaction, the history of the oceans, and environmental governance at Stanford and has supervised undergraduates on projects ranging from computer vision machine learning models for marine mammal monitoring to expert interviews of marine protected area officials. Ryan has also been an Ethics in Society Fellow with the McCoy Family Center for Ethics in Society at Stanford. Learn more at https://ryanoconnorresearch.com
Prior to his work at Stanford, Ryan served as an officer in the US Navy working on international logistics policy research and development. Ryan most recently worked as an environmental policy consultant and geospatial project manager for AECOM Technical Services, helping to administer the National Flood Insurance Program, leading multi-hazard mapping, policy analysis, and legislative affairs efforts in support of disaster and climate resilience across the United States.
Ryan earned his Bachelor's Degree in Environmental Science from the University of Virginia in 2017. -

Franklin M. ("Lynn") Orr, Jr.
Keleen and Carlton Beal Professor in Petroleum Engineering, Emeritus
Current Research and Scholarly InterestsResearch
My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
Teaching
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.
