I am a marine ecologist researching various aspects related to the structure/function and dynamics of marine ecosystems. I enjoy combining quantitative and theoretical approaches in my research, and to take a mechanistic view on biological processes for analyzing the patterns we observe. I believe that to fully understand the systems we are studying, we must not settle on describing what we see, but also study why.

I have been a permanent researcher at the IMR since January 2021, and in my current position I focus on coastal ecosystems, multiple pressures and integrated ecosystem assessments. In previous research (PhD, postdoc) I have focused primarily lower trophic levels analyzing vertical zooplankton distributions, assessing spatial (vertical) gradients in topography and light, predator-prey dynamics between zooplankton and fish, and individual-based modelling of key, Arctic copepods (Calanus glacialis, Calanus hyperboreus) in larger, numerical ecosystem models focusing on zooplankton retention and distribution. I have also been involved in the development of marine protected areas (MPAs) in the Southern Ocean through IMRs engagement in CCAMLAR.

I am particularly fond of popular science communication, and was part of Researcher Grand Prix in Bergen 2018.

Arbeidsområde

Currently, I work on the CoastRisk project where the main objective is to develop and implement an Integrated Ecosystem Assessment (IEA) framework for Norwegian coastal ecosystems. This work also involves enhancing our current understanding of ecosystems along the Norwegian coast and adjacent fjords, and identifying present and future pressures to these systems. 

I am also contributing to the modelling work in the Nansen Legacy project (www.arvenetternansen.no) research focus 4 (The future Barents Sea), where we aim to assess potential effects of climate warming on the lower trophic levels in the Barents Sea.
