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
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.

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.
