My main field of interest is dynamics of benthic coastal ecosystems with particular focus on kelp forest ecology and trophic interactions. I have long experience with environmental monitoring, with particular focus on ecological effects from eutrophication and climate change. Through my work I have coordinated national and international research and monitoring projects. I have conducted field work and cruises, using diving as a scientific tool all along the Norwegian coast. I have long experience with communicating science to the management, society and for educational purposes from an ecosystem perspective.
