  • Taxonomy and ecology of cyanobacterial from relatively natural habitats, under human impact. Traditional and molecular study of cyanobacterial.
  • Modern taxonomy of diatoms (Bacillariophyta) using the Scanning Electron Microscopy.
  • Algae as indicators of various environmental features and their use in biomonitoring.
  • Biological assessment of water quality (springs, rivers, lakes, peat bogs, post-mining reservoirs) based on diatom assemblages.
  • Influence of active compounds and biocides on the development of cyanobacterial and algal biofilms.
  • Cyanobacteria and algae as a corrosive factors of building materials and historical objects.
