Research Overview
My main interst is decision-making under uncertainty. I focus on logistics and energy modelling.

Current Research
I am particularly focussed on how uncertainty affects optimal solutions in stochastic integer programs. Just now I am working on stochastic network design and facility layout.
I am also starting to look into energy problems, partly by creating contacts with UK companies and organizations, partly by re-establishing Norwegian ties.
Research Interests
Decision-making under uncertainty
- Stochastic programming
- Stochastic network design
