Background

Most of my work is centred around modelling towards understanding the population dynamics and ecology of the large, commercially important fish stocks in the North, Norwegian and Barents Seas. I have a formal background in oceanography and employ that to study the effects of climate fluctuations on fish populations and marine ecology more generally. Chairing the ICES Cod and Climate Change working group and serving on the international steering committee of the GLOBEC programme (www.globec.org) has broadened my scope beyond Norwegian waters, while getting the opportunity to contribute to cross-cutting review articles and books has opened my eyes to the importance of comparative studies, also between aquatic and terrestrial systems.

Although I have been working at CEES for many years I am employed by the Institute of Marine Research (IMR) as a Principal scientist, with an adjunct position at CEES. Being employed by IMR naturally leads to applied management oriented work. During the last years I have been heavily involved in developing Integrated Marine management plans, first for the Norwegian Sea and now for the North Sea.

 

Scientific pledge

I have read and promise to adhere to the NENT.

Projects

Current projects include “Adaptive management of living marine resources by integrating different data sources and key ecological processes (ADMAR): A joint effort by IMR and CEES", "Spatiotemporal Variability In Mortality and growth of fish larvae in the Lofoten-Barents Sea ecosystem  (SVIM)", and "Quantifying natural variability in spawning and survival of Northeast Arctic haddock".
