• 1995 – M.Sc. (Limnology) – Faculty of Biological Sciences, University of South Bohemia, České Budějovice

• 2003 – Ph.D. (Hydrobiology) – Faculty of Biological Sciences, University of South Bohemia, České Budějovice

• 2015 – habilitation (Hydrobiology) – Faculty of Biological Sciences, University of South Bohemia, České Budějovice

 

Employment

• Since 1998 – research associate at the Institute of Hydrobiology, Biology Centre AS ČR, v.v.i.

• Since 2007 – lecturer at the Faculty of Science, University of South Bohemia, České Budějovice

 

Main research areas

• phytoplankton dynamics, function and diversity

• reservoirs limnology, phytoplankton blooms, diatom ecophysiology

• reservoir spatio-temporal heterogeneity

• analyses of long-term limnological datasets

• effects of disturbances on phytoplankton structure and composition

• interactions between phytoplankton and bacteria

• in situ application of modern fluorescence assays and image analysis

• photography – from microorganisms to aerial views of whole ecosystems

• knowledge dissemination and public communication

 

Membership in scientific organizations

Czech Limnological Society, Czech National Committee of LTER

 

Other activities

Science popularization, in particular via photography exhibitions and public presentations. Microphotographs of freshwater algae and cyanobacteria have been repeatedly published in numerous textbooks and journals. They also received various Czech and international awards (e.g. Olympus Bioscapes, Nikon Microworld).
