THUNDER: Fostering Trust in AI-Driven Healthcare
SecUre and uNbiased knowleDge-guided gEneRative AI — Generative AI, particularly large language models (LLMs), can synthesise realistic healthcare datasets to address data scarcity, but its adoption is held back by concerns about semantic validity, fairness, bias, fidelity, privacy, and real-world utility. THUNDER aims to forge a comprehensive framework for trustworthy and responsible generative AI in healthcare, with sepsis as its target clinical application.
Funding Support

European Union · Marie Skłodowska-Curie Actions
THUNDER has received funding from the European Union’s Horizon Europe Research and Innovation Programme under the Marie Skłodowska-Curie Actions (MSCA), Grant Agreement No. 101236749, with an EU contribution of €771,540. The project involves 154 staff secondments across the consortium.
The Challenge
Machine learning offers transformative opportunities for healthcare, from precision medicine to operational optimisation, but progress is constrained by limited access to diverse, high-quality data, made worse by fragmentation, data scarcity, and strict privacy regulations. Off-the-shelf generative AI can create synthetic data, but it is not ready for clinical use. THUNDER addresses four key gaps:
- No standardised frameworks for evaluating synthetic data
- Trust deficits in healthcare generative models
- The resource intensiveness of current approaches
- Design-induced opaqueness in AI decision-making
The THUNDER Framework
Anchored in expert medical knowledge, the framework rests on three Research Initiatives that together support safe and reliable generative AI:
RI-1. Standardised Evaluation
The Ruler. Comprehensive metrics for evaluating synthetic healthcare data, covering fidelity, utility, and privacy, as well as semantic validity and fairness.
RI-2. Knowledge-Guided Generation
The Engine. Generative models that use RAG, LLMs, and expert-defined domain knowledge to produce trustworthy, clinically relevant synthetic data.
RI-3. Frugal & Interpretable Design
The Vehicle. Resource-efficient models that are interpretable by design, using approaches such as neural architecture search (NAS), spiking neural networks (SNNs), and explainability.
Target application: sepsis. THUNDER focuses on sepsis, a WHO-designated global health priority, to demonstrate and validate the framework’s real-world clinical impact.
