PhD Researcher — Université de Liège (ULiège)

My research sits at the intersection of Generative AI and Digital Twins, focusing on how generative models can reconstruct, complete, and reason over incomplete spatial and semantic data in urban infrastructure. Alongside publishing, I serve the research community as a peer reviewer for IEEE journals.

DOI: 10.1109/ACCESS.2026.3717418

This review explores how Generative Artificial Intelligence can advance Underground Utility Digital Twins by addressing incomplete data, missing geometry, semantic inconsistencies, and uncertainty. It presents a task-oriented framework connecting Generative AI approaches to data synthesis, geometry and topology reconstruction, semantic enrichment, multi-source data fusion, and uncertainty quantification, alongside a conceptual Generative-Enhanced Underground Utility Digital Twin (GE-UUDT) architecture.
