I am a hydrobiologist interested in (1) fish ecology in diverse environments and (2) greenhouse gas fluxes in freshwaters, primarily using advanced underwater acoustic techniques. Besides scientific echosounders and imaging sonars, I have significant experiences with active and passive fisheries techniques (various kinds of netting and electrofishing) and field sampling of diffusive and ebullitive fluxes of greenhouse gases. I have participated on a great deal of projects focused on quantitative and qualitative investigations of fish communities and greenhouse gases in large inland and sea waters throughout Europe (Austria, Czechia, Germany, Greece, Hungary, Netherlands, Norway, Spain). I am also dedicated to the popularization of science.
