# Andreas Lothe Opdahl

Andreas Lothe Opdahl (born 1964) is a Norwegian computer scientist and Professor of Information Systems Development at the University of Bergen, known for his theory about Security requirements engineering, and for with Guttorm Sindre coining the term Misuse case.

## Life and work

Born in 1964, Opdahl received his M.Sc. in Computer science in 1988 from the Norwegian Institute of Technology (NTNU), where in 1992 he also received his PhD in computer science with the thesis, entitled "Performance engineering during information system development."
In 1985 Opdahl had started working as systems developer. He was lecturer at the Norwegian Institute of Technology from 1988 to 1992. In 1992 he was appointed Professor of Information Systems Development at the University of Bergen in the Department of Information Science and Media Studies. There he also directs the research group for Intelligent Information Systems (I2S).
Opdahl's research reflects a long-term interest in how conceptual and other types of models can support the development and management of ICT systems. His recent research investigates knowledge graphs, ontologies, large language models and their responsible uses in combination with other AI techniques in the media sector.
