Nutrient cycling in mountain forest and alpine soils, impact of soil chemistry on freshwater quality Ph.D. – 2006 University of South Bohemia in České Budějovice, Faculty of Science. Thesis: Impact of soil characteristics on water chemistry of acidified mountain lakes in the Bohemian Forest and the Tatra Mountains. Since 2007 postdoc and research assistant at HBI and Faculty of Science, University of South Bohemia. Projects: Phosphorus leaching from undeveloped alpine soils: Biotic or abiotic control? (2020-2022; The Czech Science Foundation) What are the main mechanisms affecting N flow through soil N pools in N saturated mountain soils? (2009-2011; Grant Agency of the ASCR)
