Kaj Hänninen, Senior Lecturer


Dr. Kaj Hänninen's current research is focusing on functional safety and security of embedded real-time systems. He is a senior lecturer giving courses and working in the DPAC (Dependable Platforms for Autonomous systems and Control), SafeCOP (Safe Cooperating cyber-physical systems using wireless communication), Serendipity (Secure and dependable platforms for autonomy) and PROMPT (Professional Master's in Software Engineering) projects. 

He was the main applicant and the project leader of the CloSS project (Closing the Safety-Sequrity gap in software intensive systems). The project focused on closing the safety-sequrity gap in software intensive systems. It was a collaboration between academia and industy (Mälardalen University, Saab, Volvo CE, Tetra Pak and Bosch).

In 2008 Kaj completed his Ph.D. studies and left academia temporarily to return in 2013. Throughout the years he has been working with design and systems engineering, project management and various aspects of functional safety. Some positions he had include: 

Safety Manager and Global V&V Team-Lead at Bombardier Transportation: Working with functional safety and V&V of propulsion control systems for rail vehicles. Main responsible and global team-lead (in Sweden, Germany and Switzerland) for V&V of converter platforms for light rail, passenger trains and locomotives. Experience of EN50126, EN50128, EN50129, EN50159 and EN50155 

Safety Manager and Systems Developer at Arcticus Systems: Working with functional safety and certification of operating systems for road vehicles. Experience of ISO26262 and ISO12207

Safety Critical Software Developer at CrossControl: Working with functional safety for Human Machine Interfaces and Communication for rail vehicles. Experience of IEC61508 

Kaj has also had positions as consultant and systems expert coaching designers and architects in development of safety critical software. He has been responsible for managing safety audits and reviewing a number of forthcoming safety standards. He has also given courses in safety awareness for the industry. Kaj was part of the team that developed the first SIL certified graphical human machine interface for train control management systems. He was also the lead designer for the next generation SW architectures used in product lines at a word leading manufacturer of welding equipment.

Kaj´s previous research on component models and analysis methods have been implemented in commercial tools that are now used by various companies in the vehicle domain. The research was recognised (in the university’s evaluation for improved research quality (MER14)), as a notable example on successful transfer of research result to industrial use.

He is regularly involved in writing applications for research funding. He has contributed to the following project applications: DPAC (Dependable Platforms for Autonomous Systems and Control), FIA-PiiA (Strategic Research into Safety and Security for the Automation Industry), S4PiiA (System of Systems Safety and Security in Process Industrial IT and Automation, HASIT (Harmonising Risk Analysis of Functional Safety and IT-Security), ERoSS (Efficient Reuse of Safety Critical Legacy Software), S4 (Self-Safe Systems of Systems), RAASS (Risk Analysis of Autonomous System of Systems), CloSS (Closing the Safety-Sequrity gap in software intensive systems), SERENDIPITY (Secure and dependable platforms for autonomy).

Kaj was recognised as a strategic recruitment to strengthen the research within the 8-year research profile DPAC

Kajs research has been performed in cooperation with the following companies: Bombardier Transportation, Volvo Construction Equipment, ABB Corporate Research Center, ABB Control Technologies, ABB Robotics, SICS, Saab Avionics, Saab Surveillance, Bosch, Tetra Pak, Atlas Copco, Boliden, Safety integrity, BAE Systems Hägglunds, MECEL and Arcticus Systems

Kaj has been the assistant supervisor of two doctoral students. Dr. Andreas Johnsen and Dr. Jiale Zhou. Both finished in January 2018. He is now the assistant supervisor of Malina Adach.

Current activities include:

Research on 1) Combined risk analysis approaches considering safety and security, 2) Ontologies for security informed hazard analysis of safety critical systems

Supervising doctoral student Malina Adach

Recently finished activities include:
