The main focus of my scientific interest over the past ten years is on the analysis of matter and energy fluxes exchanged between wetland ecosystems and the atmosphere using eddy covariance method. I investigate how this differs the dynamic of the GHG fluxes (CO2, CH4) at different type of wetlands covered by different types of vegetation. In my research, particular emphasis is placed on micro-meteorological aspects, biogeochemical cycles and on extreme events as well.
