My research interests concern the molecular mechanisms and mode of actions underlying the toxicity of environmental pollutants, and how this may manifest across biological organizations and produce higher level effects (organism, population). My research focuses mainly on marine organisms, and central topics within my current research activities include endocrine disruption, nuclear receptors, biomarkers, bioassays, microplastics, integrative genomics/toxicogenomics, chemicals of emerging concern, and cocktail effects.

I am currently leading the University of Bergen’s network for marine plastic pollution (Plastics Network). This network embraces cross-disciplinary research concerning plastic and microplastic pollution in our oceans, encompassing the investigation of the presence, distribution, and effects of plastic pollution, as well as its societal, legal, and health implications.
