Research Scientist, Geo-Physics Machine Learning; Hybrid Eligible

Research Scientist, Geo-Physics Machine Learning (Hybrid Eligible)

We are seeking a Research Scientist who will support a growing portfolio of research in cutting edge physics-based machine learning, geophysical modeling, spatial and spatiotemporal methods. The candidate is expected to immediately contribute to uncertainty estimation in geophysical models and broader national security research initiatives. This position offers an exciting opportunity to leverage modern concepts of physics-informed machine learning, explainable AI, and for geophysical applications related to earth system modeling, geohazards, including but not limited to earthquakes, landslides, and volcanic activity.

In addition to model development, research activities include the design of evaluation protocols that capture domain knowledge and sponsor application requirements.

Under the guidance of senior research scientists, the selected applicant will take roles on multidisciplinary teams supporting new research and engineering using ORNL’s Frontier exascale supercomputer for its dense GPU-based HPC resources to deploy models and create large-scale production datasets for high-impact sponsor missions. The candidate will be expected to handle sponsor requirements and develop rapid prototypes to demonstrate new innovations.

This position resides in the GeoAI Research Group in the Geographic Data Science Section, Geospatial Science and Human Security (GSHS) Division, National Security Sciences Directorate, at ORNL.

• Develop and implement physics-informed machine learning models for geophysical modeling, earth system modeling and geohazard prediction and assessment.
• Design algorithms integrating geophysical principles with explainable and interpretable AI techniques to enhance model interpretability and uncertainty quantification.
• Contribute to building visualizations and interfaces to communicate AI model decisions and uncertainties to diverse stakeholders.
• Contribute to research proposals, publish in high-impact journals, and present at international conferences.
• Collaborate with interdisciplinary teams to advance interpretable AI applications in geophysical and geoscience research.
• Ensure compliance with ORNL policies, standards, and procedures in all research activities.

• PhD in Geophysics, Earth Sciences, Computer Science, or a related field with a focus on computational geosciences.
• Two years of applied experience (professional or academic lab setting).
• Strong background in machine learning, artificial intelligence, and explainable AI techniques.
• Proficiency in scientific programming with experience in implementing interpretable ML models in Python and Tensor Flow/PyTorch.
• Experience with geophysical data analysis, interpretation, and the application of AI/ML in geosciences and geophysics.
• Excellent written and verbal communication skills, with ability to explain complex AI concepts to diverse audiences.

• Expertise in one or more geohazard-related fields (e.g., seismology, volcano logy, landslide dynamics, earthquakes).
• Experience with physics-informed neural networks or other physics-based machine learning approaches.
• Knowledge of uncertainty quantification and interpretation in geophysical modeling.
• Familiarity with explainable AI techniques such as SHAP, LIME, or attention mechanisms in the context of scientific applications.
• Experience in developing interactive dashboards or visualizations for AI model interpretation.
• Track record of peer-reviewed publications in explainable AI, geophysics, and/or machine learning.
• Demonstrated ability to work in interdisciplinary teams and communicate AI insights to non-AI experts.

• Q or L clearance:
  This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.
• Visa Sponsorship:
  Visa sponsorship is not available for this position.
