Research oriented in analysis and modelling of hydrological processess, historical and current changes of river networks and riverbeds, water quality assessment and modeling and application of GIS and remote sensing in physical geography. Applied research on modelling the water quality changes in large rivers and evironmental risk assessment.

Lectures on Application of Geoinformatics in Physical Geography, Surface Water Quality, Seminar on Hydrology and participating in Seminar on Physical Geography. Leading pregraduate and PhD Students oriented in hydrology, water quality, remote sensing and modelling in physical geography. 

Leading of research projects :  "Long-term changes of river ecosystems in floodplains affected by extreme floods" (Ministry of Environment of the Czech Rep., VaV-SM/2/57/05 , 2005-08).“Assessment of environemtal changes impact on flood extent“ (GAČR 205/03/Z046, 2003-2004); „Modelling the nonpoint pollution sources under conditions of global change“ (COST Action 634, 2004-07, EU coordinator A-V. Auzet, ULP, Strasbourg, France), „Soil erosion and global change“ (COST Action 623, 2002-03 EU coordinator J. Boardman, Oxford, U.K.), “Modelling the nonpoint pollution sources” (GAČR 205/00/P052, 2000-03), Evaluation of specific pollution load in Berounka river basin (GAUK 211/2001 B GEO, 2001-04). Cooperating in number of  research projects, i.e. Research Plan “The Geographic Structure and the Development of the Interactions Between the Environment and the Society” (MSM 113100007, 1998-2004, head P. Dostál), Center for Earth Dynamics Research - Experimental research of dynamics of the Earth and Earth' surface (LN00A005, 2000-04, head J. Kostelecký, VÚGTK).
