Prof. Dr. Stefan Leue

Stefan Leue has been a professor for Software and Systems Engineering at the Department of Computer and Information Science at the University of Konstanz since 2004. In 2022 he was elected as a member of the Extended Directorate of the Centre for Human | Data | Society. After studying Computer Science and Economics at the University of Hamburg, he received his doctorate in 1995 (thesis: Methods and Semantics for Telecommunications Systems Engineering) at the University of Bern (Switzerland). From 1995 to 2000 he was first an assistant Professor and then a tenured associate professor in the Department of Electrical and Computer Engineering of the University of Waterloo (Canada). In 1998 he was a member of technical staff at Bell Laboratories in Murray Hill, USA. From 2000 to 2004 he was a professor of Computer Networks and Telematics of the University of Freiburg. Since 2007 he has been a member of the Steering Committee of the SPIN Symposium on Model Checking of Software (SPIN) Since 2018 he has been a member of the Cluster of Excellence Centre for the Advanced Study of Collective Behaviour. Stefan Leue has expert knowledge in Legal Tech, Formal Reasoning, Machine Learning as well as general Software and Systems Engineering. His research focuses on the use of formal methods in the design and analysis of complex systems, with a special focus on embedded software systems and system architectures, the algorithmics and application of model checking, analysis and repair of timed systems, causality analysis and data-centric software engineering.

Research Interests

Use of formal methods in the design and analysis of complex systems, with a special focus on embedded software systems and system architectures

  • verification of machine learning / AI based software
  • data-centric software engineering
  • automotive software engineering
  • analysis and repair of timed systems (TarTar)
  • formal models of collective behavior
  • formal methods in functional safety analysis (QuantUM)
  • causality analysis and fault localization (Causality Checking) 
  • legal tech
  • case studies in the design and verification of concurrent software systems (GIOP, telecommunication systems, Airbag control units, Automated Driving System (ADS) architectures)
  • algorithmics and application of model checking
  • heuristic search in system verification (directed model checking)
  • abstraction and incomplete verification techniques
  • visual specification formalisms for concurrent systems (Message Sequence Charts)
  • semantics and verification of object-oriented modeling techniques, including UML, UML-RT and SysML
  • protocol engineering and design
  • avionics and automotive software and safety enigeering (DO-178C, AutoSAR, ISO 26262, ISO PAS 21448 (SOTIF))
  • verification of real-time and probabilistic system properties (DiPro)
