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. -
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.

Lamprini Papargyri
Postdoctoral Scholar, Earth System Science
BioLamprini Papargyri is a postdoctoral scholar at Stanford University co-advised by Professor Steve Davis and Dr. Ken Caldeira. She earned her PhD in Civil and Environmental Engineering from the University of Cyprus, where she worked under the guidance of Professor Panos Papanastasiou to optimize the durability of materials used in photovoltaic systems. Her doctoral research employed advanced computational modeling using 3D finite element methods and XFEM to simulate stress, cracking, and degradation mechanisms in photovoltaic materials.
At Stanford, Lamprini’s research lies at the intersection of climate policy, economics, and equity. Her current work explores how economies with income inequality can optimally allocate resources between income redistribution and emissions abatement. Beyond research, she has led and contributed to multi-million-euro research initiatives across Europe and remains deeply interested in the societal and ethical dimensions of emerging technologies. Broadly, she is interested in developing integrated models that inform equitable and sustainable pathways for climate mitigation and economic development. -
Jack Pink
Postdoctoral Scholar, Environmental Social Sciences
BioI am primarily a marine researcher; my PhD is in maritime archaeology specifically focusing on the archaeology of ships. I have been fascinated by the sea and by shipwrecks since reading Jacques Cousteau's The Silent World as a child. The combination of diving and archaeology seemed to me then, and still seems to me now, an unusually fortunate way to make a living.
I read Archaeology and then Maritime Archaeology at the University of Southampton. I then spent two years as Assistant Rural Surveyor at the National Trust's Lanhydrock estate in Cornwall. Whilst that might look like a tangent (and it felt like it at the time) it was an experience that proved more formative than I had anticipated. My responsibilities covered a substantial portion of the Trust's Cornish portfolio, including areas of the Cornwall and West Devon Mining Landscape UNESCO World Heritage Site. Managing working harbours and conservation sites in an operational context, answerable to communities as much as to institutional objectives, gave me an understanding of coastal and marine heritage that you frankly cannot get as an academic.
I completed my PhD in 2023, under the supervision of Professor Jon Adams and Dr Julian Whitewright. I examined an assemblage of two hundred merchant vessels through the integration of archaeological remains and historical records, using this dataset to explore the impact of changing systems within the British Empire on merchant shipping and the development of shipbuilding technologies across the nineteenth century. During and around this period I worked to build the practical experience that underpins good maritime archaeology. Underwater, this took me to Roman harbour sites and anchorages in Lebanon (at Anfeh, Batroun, and Tyre) to an underwater excavation in Kalmar, Sweden, to survey projects across the British Isles from the Isle of Lewis to the Pembrokeshire coast, and to geophysical work in Uruguay. On land I directed and contributed to geophysical surveys across Europe, including at Ephesus in Turkey and at a British Museum excavation of an Indo-Roman trade site in northwest India. The range of these projects was deliberate: I was trying to become the kind of archaeologist who could work anywhere and with anything, and fieldwork in different countries and conditions is the only reliable way to do that. Something worked because I found myself being consulted on the archaeological standards for the wreck of Shackleton's Endurance following its discovery in 2022.
A period at Historic England followed, first as Senior Policy Advisor for Underwater Cultural Heritage where I supported the development of government legislation and prepared guidance on the UNESCO Convention on the Protection of Underwater Cultural Heritage. I moved to Technical Manager of the Marine Data Exchange Heritage Accelerator, where I led a team integrating offshore heritage data from commercial contractors and wind farm corporations into the National Marine Heritage Record. This work required collaborating with the Crown Estate, DCMS, and DEFRA, and gave me an understanding of how the marine sector operates commercially that sits alongside but distinct from my research background.
I joined Stanford in September 2025 as a Postdoctoral Scholar holding a joint appointment between the Stanford Robotics Center and the Stanford Doerr School of Sustainability. At the Robotics Center I manage the Oceans Flagship, a programme developing next-generation remotely operated vehicle capabilities for scientific discovery at depth, working with Professor Oussama Khatib and Dr. Steve Cousins. In parallel, I work with Dr. Krish Seetah on research into the environmental impacts of shipwrecks, exploring the interactions between anthropogenic material and the marine ecosystem within the developing field of Maritime Heritage Ecology. -
Ashley Prow Fleischer
Postdoctoral Scholar, Earth and Planetary Sciences
BioI earned a PhD in Earth Science with a focus in paleoclimatology from Syracuse University, where my research focused on reconstructing past environmental change and biotic responses using microfossils and geochemical proxies. My work integrates stratigraphy, paleobiology, geochemistry, and climate modeling to better understand Earth's climate dynamics during the intervals of rapid change, like the Late Devonian and end Triassic mass extinctions.
