Research Interests

1.Palynology, ecosystems and environment
Pollen grains are one of the most interesting elements of biosystem. They areresponsible for transfer of genetic information and health of ecosystems; the fossilpollen grains are also indicators of past climate change. In addition, pollen grains areused in forensic science to trace criminal activities including illegal business withhoney.
2.Geographic information systems to natural resource management studies
Investigating spatial patterns of natural and human phenomena such as radioactivityand its impact on human health; investigating spatial pattern of toxic elements andtheir impact on biosphere; evaluating total stem volume using terrain, satellite dataand sequential gaussian simulation.
3.Application of geostatistics in prediction of karst hazards.
The methods of kriging interpolation and variogram modeling became widely usedin natural sciences. The karst environment is prone to sudden subsidence of dolinesthat cause economical damages and pose also danger to human life. The evaluationsof parameters that lead to collapse of dolines using kriging interpolation methodscan predict the potential hazards in carbonatic rock complexes.
4.Multifactorial statistics and regional dynamics in natural ecosystems
The natural ecosystems are complex entities consisting from biotic and abioticcomponents. Multifactorial analysis can be used to evaluate causes of dynamicchanges in ecosystems and identify relatively homogeneous complexes that can bedelineated and understood with respect of their internal structure and interregionaldynamics.
