Professional career

My professional scientific career has started in 1998. Until this time I worked in different administrative and managers positions. 

From 2005 I has also taught on Charles University in Prague (Methods of abundance and biomass estimation, Special methods in ichthyology and Applied ecology).


Coordination :

- 2008 and 2009- project with Hungary acoustical observation of fish stock in Lake Balaton , consultation of data processing.

- 2011- 2012   technical-scientific cooperation with Austria, establishing the relationship between fish size and acoustic target strength for ecological studies of lakes and reservoirs: Modifications required for new species (whitefish, Coregonus lavaretus) and new frequencies (38 kHz).

- 2011-2015 -  the project of GA CR : Hydroacoustical distinguishing between fish and bubbles, and quantification of methane bubble ebullition in freshwater reservoirs of temperate zone. 

Other experiences 

-in 1999 participating  in Europe Union project Fishstrat  in Asia.

-in 2001, 10 months stay in Fisheries Research Laboratory, US Fish and Wildlife Conservation Commision, Florida, USA;

- in 2016 – participating in training course of ICES: Principles and methods of broadband/wideband technologies​


Author and coauthor of  50 publications with IF and 1 book chapter, 497 citations, H-index 14.
