Postdoc Researcher in AI: Language Models, Ontologies and Knowledge Graphs

We invite you to apply for a 2-year postdoctoral position in the area of hybrid AI, combining modern language models (LMs) with ontologies and knowledge graphs (KGs). The position is part of a newly funded 4-year research project starting in 2026, focused on domain-specific, trustworthy, and explainable AI systems.

Recent advances in foundation models have demonstrated impressive capabilities, but they still face critical limitations in reasoning, explainability, robustness, and domain adaptation. This project explores integrations of  modern LMs with ontologies and knowledge graphs to address these challenges.

The research will investigate:

• Ontology- and KG-enhanced language models
• Domain-specific language models and retrieval-augmented generation
• Knowledge grounding, constraint-aware generation, and explainability
• Evaluation methodologies for knowledge-intensive AI systems

The project will be driven by real-world domain applications in materials, casting, and manufacturing, developed in close collaboration with domain experts, ensuring both scientific depth and applied impact.

• Freedom to shape research directions and co-develop the project agenda
• Opportunities for high-impact publications and open-source contributions
• Collaboration with PhD student, domain experts and international partners
• Support for conference travel and research networking
• A stimulating interdisciplinary research environment
