Background and activities
I teach and do my research in marine sciences with focus on aquaculture, and I am responsible for NTNU's research license for salmonids in the sea.
Main research interest: understanding and describing 1) complex interactions between structures, biology and the physical-chemical environment, 2) transport mechanisms in the sea and 3) animal welfare. I like to work interdisciplinary to promote technology and knowledge transfer between research areas. Most of my work has been aquaculture related, with focus on fish welfare and environmental effects. Other areas of interest include planktology, biological and chemical oceanography; integrated aquaculture and scientific method development.
