I have spent most of my career working on research and development projects in numerical ocean modeling, on scales ranging from the Norwegian Sea down to laboratory scales of mm. I have worked on a wide spectrum of projects, from practical applications to model development, in particular as a co developer of BOM (The Bergen Ocean Model). Aspects I have been working on includes establishing models for new regions, dispersion modelling, analyzing currents, gridding, adapting forcing data to models, parallelization of codes, performance optimization of codes etc.
