My research has constantly centered into a deeper understanding of different processes and interactions in the marine microbial pelagic food web (including larger zooplankton). More specific, I have been working with marine and limnic bacterial carbon utilization and nutrient limitation in temperate and Antarctic waters, phytoplankton ecology in Swedish, Brazilian and Mediterranean marine waters (utilization of organic bound nitrogen (in connection with bacteria, heterotrophic/mixotrophic flagellates and ciliates), toxin production in dinoflagellates and cyanobacteria, and zooplankton experimental ecology (grazing on toxin producing phytoplankton and uptake of phytoplankton toxins and their effects on zooplankton egg production and survival). I have also looked at vertical migration by dinoflagellates and effects of cyanobacterial toxins on the food web in connection to decaying blooms. I have been studying the effects of increased runoff of dissolved organic matter on coastal phytoplankton, both during my PhD-thesies work and also later on.
The three main projects I am working with right now are:
- Assessing the effects on the marine pelagic food web by the invasive marine cladoceran Penilia avirostris.
- Sinking rates and phenotypic plasticity among marine phytoplankton in a warmer world.
- Temporal and spatial distribution of harbour porpoises in the southern Kattegat

- A large molecular size fraction of riverine high molecular weight dissolved organic matter (HMW DOM) stimulates growth of the harmful dinoflagellate Alexandrium minutum
- Glutathione transferase activity and oocyte development in copepods exposed to toxic phytoplankton
- Species- and stratification-dependent diel vertical migration behaviour of three dinoflagellate species in a laboratory study
- Bacterial abundance, production and organic carbon limitation in the Southern Ocean (39-62 degrees S, 4-14 degrees E) during the austral summer 1997/1998
- Effects of beach cast cleaning on beach quality, microbial food web, and littoral macrofaunal biodiversity
- Influence of solar radiation on the availability of dissolved organic matter to bacteria in the Southern Ocean
- Effect of grazing by a neotropical copepod, Notodiaptomus, on a natural cyanobacterial assemblage and on toxic and non-toxic cyanobacterial strains
- Feeding, reproduction and toxin accumulation by the copepods Acartia bifilosa and Eurytemora affinis in the presence of the toxic cyanobacterium Nodularia spumigena
