Mattias Tiger

Assistant Professor

Artificial intelligence is about automated problem solving. I develop AI and autonomous systems that operate reliably over time, handling uncertainty and change while remaining safe and trustworthy in real-world environments.

Artificial Intelligence – from theory to real-world systems

I am an AI researcher at ¸£Àû¼§, working on safe, robust, and trustworthy AI and autonomous systems. My research focuses on combining learning and reasoning to enable AI systems that can operate reliably in complex, dynamic, real-world environments.

I study trajectory modeling, motion planning, and runtime monitoring for autonomous robots and decision-support systems, with particular emphasis on uncertainty management, anomaly detection, and safety guarantees during operation. My work spans both fundamental methods and applied research in close collaboration with industry and public-sector partners, including transportation, robotics, and public safety.

​​I am Deputy Head of the Reasoning and Learning (ReaL) Lab and actively involved in national and international initiatives on trustworthy AI and autonomous systems.
