  • AI/ML for Automated Critical Materials Resource Mapping

    Ahamed – INL R&D Staff Scientist

    Research Overview

    Efficient exploration and development of critical mineral resources increasingly depend on integrating large volumes of geologic and geophysical data. Traditional log‑analysis workflows for solution‑mined deposits require detailed interpretation of lithology, stratigraphic boundaries, fluid‑flow‑controlled alteration zones, and grade‑related signals. These processes are often labor‑intensive and subject to interpreter variability.

    This project seeks to apply modern machine learning methodologies to automate essential components of mineral resource mapping. Students will work with representative geophysical and lithologic datasets to:

    • Clean and preprocess well‑log data (e.g., resistivity, natural gamma, spontaneous potential)
    • Correct depth misalignments between lithologic and geophysical logs
    • Build ML models for lithology prediction, stratigraphic correlation, and geologic zonation analysis
    • Investigate pattern recognition methods to identify alteration fronts and mineralization indicators
    • Explore workflow expansion using physics‑informed ML or sparse sensing approaches to improve mapping under limited‑data conditions

    The overarching goal is to develop scalable data‑driven methods that enhance subsurface interpretation for critical materials and solution‑mining applications.

    Student Research Experience

    Students will engage in interdisciplinary work spanning geoscience, machine learning, and data engineering. Activities include:

    • Data Integration & Preprocessing – preparing and aligning multi‑source well‑log datasets, correcting sample‑lag effects, and constructing geologically meaningful features.
    • Machine Learning Model Development – implementing algorithms such as PCA, dynamic time warping, tree‑based models, gradient‑boosting methods, and neural networks to support automated interpretation.
    • Geologic Interpretation – learning how lithologic variation, stratigraphic architecture, and fluid‑alteration signatures relate to mineral resource distribution within solution‑mined systems.
    • Model Evaluation & Visualization – generating correlation panels, prediction plots, and zonation maps to assess machine‑learning results in a geologic context.

    Students will collaborate with INL staff and gain experience applying AI/ML techniques to real‑world subsurface problems relevant to critical materials, energy security, and advanced resource extraction technologies.

  • Effect of Pressure Resistance Welded Molybdenum Alloy’s Response to Helium Ion Irradiation

    Charit – University of Idaho

    Research Overview

    The overarching goal is to explore and understand the irradiation response of pressure resistance welding (PRW) technology on two molybdenum-based materials: commercially pure molybdenum and an oxide (La₂O₃) dispersion strengthened molybdenum alloy, MoLa. The project aims to understand the effect of helium ion irradiation on the microstructural, microchemical and mechanical properties of these materials.

    There has been significant interest in the potential use of molybdenum-based materials among high melting refractory metals/alloys to produce fuel elements for the nuclear thermal rocket engine as well as accident-tolerant fuel cladding applications in advanced light water reactors. The benefits of molybdenum include its high melting point, high thermal conductivity, elevated temperature mechanical properties, and excellent corrosion resistance against liquid metals and aggressive environments.

    Student Research Experience

    The student will have the unique opportunity to learn about the potential use of refractory metals in terrestrial and extra-terrestrial nuclear reactors, and will participate in hands-on characterization of ion irradiated samples and data analysis. They will gain hands-on experience in scanning electron microscopy, energy dispersive spectroscopy and nanoindentation during the project period.

    They will also have the opportunity to observe operation of a high resolution transmission electron microscope by an instrument scientist. Near the end of the project, the student will present findings in microstructure-properties correlations via a presentation.
