Skills & Interests: 

Research interest

Taxonomy, ecology and physiology of marine protists. Special interest for biology of ciliates, toxic and non-toxic dinoflagellates, interactions between microzooplankton, phytoplankton, nano-, and picoplankton.


Isolation, cultivation and physiology of protists, including unicellular algae, mixotrophic and heterotrophic species, loricated and aloricated ciliates. Development of special culture media. Laboratory experiments using protists. Establishment of clonal mass cultures of toxic algae (Alexandrium, Ostreopsis) for the isolation and analysis of algal toxins.
The use of microalgae for biotoxicity tests. Delayed fluorescence for growth monitoring and differentiation of algal strains.
Grazing of microzooplankton in culture experiments and on natural assemblages using the dilution technique.
Light- and electron microscopic methods (TEM, SEM) for the determination and analysis of protists.
