I am involved in several different project related to phytoplankton including cyanobacteria of various types, here are a few examples:

• Phytoplankton-bacteria interaction and labile carbon transfer during different growth stages, diel cycles and temperatures using transcriptomics and metabolomics (VR International Post Doc).
• Nitrogen fixing cyanobacteria in the Baltic Sea including the use of stable isotope incubation experiments, biogeochemical models, and monitoring data (ÅForsk repatriation grant).
• Two projects on monitoring and anlyses of algal toxins, both in freshwater and seawater, mainly focusing on cyanobacteria and assimilated in mussels (Board of Agriculture).
