Research interest
- autotrophic picoplankton ecology in eutrophic freshwater reservoirs
- ecophysiology of autotrophic picoplankton (various Synechococcus/Cyanobium isolates)
- ecology and composition of cyanobacterial blooms
- isolation and cultivation of freshwater cyanobacteria
- microbial food web; cyanobacteria – protozoa interactions
- genetic (molecular) characterisation and differentiations of cyanobacteria
Research strategy
Research on cyanobacterial ecology in combination of field (including mesocosms experiments with dialyses bags) and laboratory work (light / temperature / nutrient gradient experiments) as well as of classical microbiological (isolation and cultivation) and modern molecular techniques (PCR, ARDRA, DGGE, sequencing), epifluorescence microscopy and flow cytometry.
