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. -

Leona Neftaliem
Ph.D. Student in Environment and Resources, admitted Autumn 2022
BioLeona is pursuing a PhD in the Emmett Interdisciplinary Program in Environment and Resources (E-IPER) at Stanford University. Her current research focuses on improving tree detection methods, understanding human migration patterns in response to environmental and socioeconomic pressures, and assessing drivers of urban air quality. She approaches these topics by integrating remote sensing, quantitative surveys, and innovative environmental engineering techniques at different scales and in different cities.
Before Stanford, Leona worked as a research technician at the Smithsonian Environmental Research Center, where she designed technologically innovative climate change experiments. She is a Knight-Hennessy Scholar, National Science Foundation Graduate Research Fellow, and a Stanford School of Sustainability Dean’s Graduate Scholar. -

Mark Nikolic
Postdoctoral Scholar, Earth and Planetary Sciences
BioI study large scale processes of evolution through earth history using the fossil record. In doing so, I make use of computational and phylogenetic approaches along with large datasets. I also lead the History of Life and Biodiversity summer internship through the Stanford Young Investigators program. Aside from fossils, I'm also a big fan of riding my bike and disco music.

Fridah Nyakundi
Ph.D. Student in Environment and Resources, admitted Autumn 2021
BioI am a Ph.D. candidate in Environment and Resources at Stanford University’s Emmett Interdisciplinary Program in Environment and Resources (E-IPER). My research sits at the intersection of environmental and natural resource economics and land system science, applying remote sensing and economic methods to understand how natural resource use shapes livelihoods and ecosystems in low- and middle-income countries. Currently, my doctoral work focuses on the risks and decision-making strategies in aquaculture systems, with a case study on Nile Tilapia cage farming in Lake Victoria. While aquaculture is the subject of my current research, my broader interests span natural resource management (NRM) economics, agriculture and environmental economics, land system science, and food systems resilience. Before graduate school, I spent five years at the International Centre for Tropical Agriculture (CIAT), supporting the design and execution of large-scale impact assessments and leading the setup of data systems for the Africa research team. I have been a fellow at Environment for Development (EfD) Kenya since 2017, contributing to applied water and resource economics research.

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.
