Experience 

Axel’s professional experience blends academic research with industrial applications. At TotalEnergies, as a Geologist Intern, he analyzed carbonate thin sections, interpreting petrographic features for reservoir evaluation. Later, as a Data Scientist at AGEOS, he applied hyperspectral imaging to mineralogical quantification, developing regression models and calibrating point cloud acquisitions. His current role as a Ph.D. researcher involves designing deep learning systems for carbonate reservoir characterization, focusing on semi-supervised classification, conditional synthetic dataset generation, and multiscale image segmentation. He has also explored model explainability, ensuring AI decisions are interpretable for geological experts. Additionally, Axel has worked on integrating bi-modal classification models combining imagery with petrophysical data, as well as anomaly detection frameworks. His cross-domain expertise enables the translation of AI methodologies into practical tools for geoscience, creating value both in research and industrial operations.

Research Focus 

Axel’s research lies at the convergence of computer vision, deep learning, and carbonate petrography. His primary objective is to enhance geological image analysis through advanced AI-driven methodologies. Key areas include representation learning with invariance to interpretation biases, synthetic dataset generation conditioned on geological parameters, and domain adaptation to bridge synthetic and real-world imagery. He specializes in texture synthesis, pixel harmonization, and object packing strategies for creating high-quality training data when labeled datasets are scarce. His work also involves developing heuristics-based regularization techniques for improved segmentation accuracy and integrating statistical analysis to link image descriptors with petrophysical properties. By leveraging semi-supervised and multi-modal approaches, Axel aims to create robust and generalizable AI models that address challenges in reservoir characterization. This research not only advances geological sciences but also contributes to broader AI applications in image-based data interpretation across environmental and industrial domains.
