  • Josheena Naggea

    Josheena Naggea

    Postdoctoral Scholar, Earth System Science

    Current Research and Scholarly InterestsJosheena's community-engaged research focuses on small-scale fisheries, disaster impacts and recovery, marine protected area management, and the valorization of natural and cultural heritage in ocean governance. She has a keen interest in understanding people-ocean connections and how that influences pro-ecological behavior and local environmental stewardship.

  • Alireza Namayandeh

    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.

  • Dr. Mahendra Nimmakanti

    Dr. Mahendra Nimmakanti

    Postdoctoral Scholar, Earth System Science

    BioI am a climate scientist with academic training spanning meteorology, oceanography, and climate dynamics, holding an M.Sc. in Meteorology and an M.Tech. in Atmospheric Sciences from Andhra University, and a Ph.D. in Atmospheric and Oceanic Sciences from NIT Rourkela, where my doctoral research focused on monsoon variability and climate dynamics.
    My research integrates advanced climate modeling (CESM2, RegCM5, WRF), large-scale diagnostic analysis, and high-performance computing to investigate the dynamics of the Indian Summer Monsoon, AMOC–monsoon teleconnections, ENSO interactions, tropical–extratropical coupling, and sub-seasonal to seasonal prediction. I have developed specialized diagnostic frameworks for identifying climate system transitions and tipping elements, and have collaborated actively with international research groups across Europe, North America, and South Asia. My work has appeared in peer-reviewed journals.

    Postdoctoral Scholar, Earth System Science

    Current Research and Scholarly InterestsBy recreating high-resolution flood maps for the last 50 years in California, my research aims to cross-correlate flood hazard maps with medical records to investigate whether a causal relation exists.

  • Lamprini Papargyri

    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.
