• Applications to subsurface imaging, industrial inspection, and sensor data

• Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, Computational Science, or a closely related field, with a focus on explainable AI or interpretable machine learning.
• Demonstrated research experience in explainable AI and deep learning, including one or more of:
  • • Model interpretability (e.g., saliency methods, attribution, feature importance)
    • Explainability techniques for neural networks
    • Interpretable model design
• Experience with 3D data (e.g., volumetric imaging, point clouds, or spatiotemporal data) and deep learning methods such as CNNs, transformers, or graph neural networks.
• Proven experience in segmentation, classification, or anomaly detection tasks.
• Strong programming skills in Python.
• Hands-on experience with machine learning frameworks such as PyTorch or TensorFlow.
• Strong analytical, problem-solving, and communication skills.
• Ability to work effectively in multidisciplinary teams.

• Experience with XAI methods for computer vision or 3D data.
• Familiarity with uncertainty quantification, probabilistic ML, or Bayesian deep learning.
• Experience with large-scale data processing and GPU-accelerated training.
• Knowledge of evaluation metrics for explainability and model trustworthiness.
• Experience applying AI to engineering, geospatial, industrial, or scientific datasets.
• Strong publication record in XAI, machine learning, or computer vision.
• Demonstrated ability to translate research into decision-support applications.

• Passion for developing trustworthy and interpretable AI systems.
• Interest in solving high-impact, real-world problems involving complex data.
