Reasoning and Learning Lab
Division of AIICS · Department of Computer Science (IDA)
Linköping University, Sweden
We develop hybrid AI systems that combine machine learning, reasoning, and planning to create trustworthy, safe, and robust AI for real-world applications—from autonomous systems and healthcare to education and public safety.
About the Lab
The Reasoning and Learning Lab (ReaL) is a research unit within the Division of Artificial Intelligence and Integrated Computer Systems (AIICS), Department of Computer and Information Science (IDA), Linköping University.
Our research focuses on Trustworthy AI, autonomous systems, stream reasoning, and the intersection between knowledge representation and machine learning. We build AI that is not only powerful, but also safe, robust, and transparent—systems that work reliably in complex, dynamic, real-world environments.
The lab is led by Professor Fredrik Heintz, who also serves as Head of the AIICS Division, Director of WASP's Graduate School, Program Director of WASP-ED, and Director of LiU's AI initiative.
Research Areas
Trustworthy AI
Developing AI systems that are safe, fair, transparent, and robust. Coordinator of the EU TAILOR network and the TrustLLM project for open European language models.
Autonomous Systems
Motion planning, trajectory modeling, and runtime monitoring for autonomous robots and drones with safety guarantees. Collaborative projects with Saab, Ericsson, and Swedish Transport Administration.
Stream Reasoning
Real-time reasoning over continuous data streams for time-critical applications, combining formal methods with probabilistic approaches for anomaly detection and decision support.
Applied AI & Education
Deploying AI in healthcare, transportation, logistics, and public safety. Leading national AI education initiatives through WASP-ED and AI Academy.
Neuro-Symbolic AI
Bridging learning and reasoning: combining neural networks with symbolic knowledge representation for systems that generalize, explain, and verify their decisions.
Cybersecurity & Resilience
Developing AI resilient to adversarial attacks. Hosting the national SSF RESIST center (SEK 60M) for cyber-resilient AI systems.
Selected Projects
National center for developing resilient AI systems, protected against cyberattacks. SEK 60 million. Directed by Fredrik Heintz.
Developing a trustworthy, open, and sustainable large language model for European languages including Swedish.
European collaboration building open LLMs via the ALT EDIC consortium.
Multiple PhD and postdoc projects funded by the Wallenberg AI, Autonomous Systems and Software Program, including WARA, NEST Cybersecurity, and NEST WISE initiatives.
Dynamic multi-robot planning and adaptive autonomous systems for industry and transportation.
Wallenberg Transformative Technologies Education Development Program. Transforming university education with AI across Sweden.
The lab currently manages 25+ active funded projects from funders including WASP/KAW, EU Horizon, SSF, Vinnova, VR, ELLIIT, and LiU strategic initiatives.
