Souradeep Mukherjee
Ph.D. Student in Earth and Planetary Sciences, admitted Autumn 2023
BioSouradeep is an Exploration Geologist-turned-AI Researcher developing decision-making algorithms to discover high-grade mineral deposits. With almost a decade of experience in on-field exploration of critical & strategic mineral deposits, he is now using his computer to unlock the full potential of mineral discovery.
Souradeep is currently a Doctoral Researcher at Stanford Mineral-X. His current work focuses on fusing multi-element soil geochemistry with 3D geological inference to build predictive models for subsurface intrusion-hosted Ni-Cu sulfide mineralization in the Curaçá Valley, Brazil. By leveraging machine learning, geostatistics, and compositional data analysis, he aims to reduce geological uncertainty and operational costs in mineral targeting, transforming how exploration is conducted in under-explored terrains.
Prior to Stanford, Souradeep held several technical and supervisory roles at the Atomic Minerals Directorate for Exploration and Research (AMD), Government of India, where he spearheaded multiple national-scale mineral exploration campaigns. He led the exploration and evaluation of uranium-bearing sediments in the Bhima Basin, the mapping of lithium-rich pegmatites in Karnataka, and the delineation of heavy mineral sand deposits across the east coast of India. His work included advanced geological mapping, structural interpretation, kinematic analysis, downhole geophysics, petrological microscopy, and geostatistical modeling—skills that now enrich his algorithmic thinking in research.
His research interests span compositional data analysis, geospatial modeling, machine learning for Earth systems, building intelligent decision making agents for mineral exploration and mineral prospectivity analysis. He is particularly passionate about bridging the gap between traditional geosciences and computational intelligence to power the next generation of resource discovery tools.
When he’s not deep into code or core samples, Souradeep contributes to scientific outreach, mentors young geoscientists, and advocates for data transparency and sustainability in the mining sector. He is also a writer, a poet and loves to write pieces on existential philosophy. -

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.
