Short biography Max 160 characters [0/160]
Interests and engagementsI am currently director of the Rolls-Royce University Technology Centre (UTC) "Performance in a Seaway", see www.ntnu.no/imt/forskning/rolls_royce for more information. A related activity is the Research Council sponsored research project on propulsion in a seaway - SeaPro www.ntnu.no/imt/forskning/seapro
I am currently engaged in the planning of the new marine technology research center in Trondheim - www.worldoceanspace.com
I am coordinator for the hydrodynamic laboratories in the Department of Marine Technology.
Other topics of interest are:
- Model test techniques
- Resistance and propulsion
- Performance of high speed marine vehichles, especially air cushion catamaran
