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. -

BioPlants display enormous diversity of forms today that, have evolved over geological timescales after plants successfully colonized land. Currently, I am interested in learning more about evolutionary changes in plant structures including specialized reproductive organs of seed plants. I study plant fossil record from deep time and living plants with the aim to develop a better understanding of origins of plant reproductive structures and drivers of morphological evolution in plants. Previously, I have looked at spore-pollen record preserved in sedimentary rocks from Canada. These microscopic fossils and their distribution in space and time can help us elucidate the response of vegetation to past extinction events.

BioI grew up in Curitiba, a city in southern Brazil, and, moved to Rio de Janeiro to join the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) years ago.
I have a strong grasp of the oil and gas industry, where I have been working for more than 15 years. I have a bachelor’s and master's degree in geology from the Federal University of Parana, Brazil and, I have become a public servant of the ANP, where I have held different technical and managerial positions. I spent these past 15 years working on the ANP’s large-scale strategic projects, conducting a geological evaluation for Brazil’s bidding rounds, and developing a multiyear geological and geophysical data acquisition plan for the Agency. I was also responsible for coordinating the first phase of the onerous assignment process, which authorized the Brazilian Government to onerously assign to NOC Petrobras up to 5 billion barrels of oil. I have also been directly involved in the location of two wells, which discovered two of the country's largest oil fields (Buzios and Mero fields). As a geologist researcher, my main objective aims at acquiring capabilities and developing the knowledge required to manage reservoirs to maximize oil recovery and extend the lifespan of oil fields as well as acquire a solid understanding of oil reservoir management to bring innovative knowledge to Brazil and help create guidelines to monitor oil field development and production in my country.
