Nygårdsgaten 112, 5008 Bergen, Norway

I work on the maths/stats behind:

Data assimilation
Robust optimization

Applications that I have expressly worked with:

Chaotic weather dynamics, climate
Subsurface petroleum flow

My work is mostly on the theory side, with strong guidance and support by numerics.
