Research

Most of my research is on knowledge graphs and multimodal ML for cultural heritage, with some work on data interoperability in human biomonitoring.

Research themes

Cultural heritage

Heritage institutions hold vast collections of digitised objects — paintings, manuscripts, archaeological finds — that are rich in meaning but often poorly connected. I work on making that cultural knowledge more discoverable and reusable, using knowledge graphs to link objects across collections and multimodal ML to bridge the gap between visual content and structured metadata.

Knowledge graphs

Knowledge graphs provide a principled way to represent, integrate, and query heterogeneous knowledge. My work focuses on building and using KGs that combine domain expertise with data-driven methods — from ontology design and linked data publishing to knowledge-enhanced retrieval and recommendation.

Biomonitoring

Human biomonitoring studies generate complex datasets across multiple European research consortia. During my time at VITO, I worked on improving the interoperability of these datasets — harmonising variables, aligning vocabularies, and building tools that let researchers query across study boundaries.

Network security

My master's thesis explored deep reinforcement learning for network intrusion detection. While my focus has since shifted, this work gave me a solid grounding in applied ML and a lasting interest in how intelligent agents can operate in adversarial environments.
