I am a marine ecologist studying various aspects related to the productivity, structure 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. My research methods are wide, and span from statistical analyses of complex datasets, to simple theoretical models of ecological processes and more advanced numerical models coupling biological processes with ocean circulation.

I have been a permanent researcher at the Institute of Marine Research since January 2021, and have experience from buisness management, HR, nature consultancy/conservation, communication and public management from studies and positions held before I started a PhD in 2016. 

I am particularly fond of popular science communication, and have contributed to a range of talks and public outreach over the course of my career.

Arbeidsområde

Currently, my rearch focuses largely on Norwegian coastal waters and to some degree polar ecosystems (Barents Sea). I am the principal investigator in a recently funded research project (PELAGIC, Norwegian Research Council) where our primary objective is to assess how temperature and water clarity affects planktonic size structure, dynamics and the competitive relationship between visual and tactile planktivore predators in coastal ecosystems. I also work with integrated ecosystem assessments (IEA) and ecosystem risk assessments (ERA), aiming at strengthening the ecosystem approach to marine management. I am part of the NORWECOM.E2E modelling team at the IMR and collaborate in model development and analyses, in particular to individual-based modelling of key calanoid copepods in the Nordic Seas.
