Motto of my research:
"Describe universe on two pages and make at least two examples"
by my favorite geochemist Steve Norton, Univeristy of Maine

My research has been focused before all on various environmental gechemical problems. My research begun with geochemistry of waters with respect to toxic metals such as  Be, Al and Pb. Envrionmetal topic in the Czech Republic was the acidification, its effects on environment and connected problems - the Czech Republic belongs to the areas with the greatest damage to the environment by acidification in the 20th century. In recent years, my work has focused particularly on the links between climate change and mercury cycling. I am interested in how climate‑driven changes—such as shifts in temperature, precipitation regimes, extreme events, and ecosystem functioning—affect the mobilization, transport, and storage of mercury in terrestrial environments. Tree‑ring archives play a key role in this research by offering insights into historical mercury inputs, long‑term trends, and potential lagged responses of forest ecosystems to both climatic and anthropogenic drivers. More broadly, my research aims to integrate tree‑ring records with other environmental data, including soil, atmospheric, and hydrological information, in order to better understand mercury dynamics across different spatial and temporal scales. By combining field observations, analytical geochemistry, and interdisciplinary interpretation, I seek to improve our understanding of feedbacks between climate variability, ecosystem processes, and contaminant cycling.

Looking ahead, I am keen to further develop research that connects tree‑ring archives, climate change, and mercury biogeochemistry, particularly in a comparative or cross‑regional context. I see strong potential for collaborative work that links natural archives with contemporary monitoring and modeling approaches, contributing to both fundamental knowledge and applied questions related to environmental risk assessment and long‑term pollutant legacies.

Great deal of my research including my masters and doctoral thesis has been connected to the Lesni potok catchment. 

I am using the results of my geochemical research within teaching of subject "Heavy Metals in the Environment" at the Charles University, Prague.
