Affiliation

I am a research professor and head of the Secure and Trustworthy Intelligent Systems (SENTRY) department at Simula Research Laboratory in Oslo, Norway. I am also Head of AI Security at Simula’s Centre for AI Security and Safety (CAISS).

From 2019 to 2025, I was head of Simula’s Data-Driven Software Engineering department (dataSED). In 2026, the department moved to Simula’s Cyber Security Division and became SENTRY, in line with its increased focus on security and on AI.

Contact me if you are interested in discussing opportunities to work with us on addressing concrete software engineering needs in industry and society based on evidence-based research results.

Before moving to Norway, I worked in the Software Engineering Research Group at Delft University of Technology, the Netherlands, and in (what is now) the Software Analysis and Transformation group at the Centre for Mathematics and Computer Science (CWI) in Amsterdam, the Netherlands. Collaborations in both these groups have helped to shape my research interests in exploring novel techniques that are aimed at addressing real-life software engineering challenges.

I am co-founder of the Software Improvement Group (SIG), a company that helps organizations deal with software (legacy) issues by means of automatic source code analysis, software risk assessments, software monitoring and automatic (re)generation of technical documentation based on source code analysis. Starting with a small team of 6 people in 2000, SIG has grown to employ over 150 people and became a key player in evidence-based software quality improvement.
