Research in the Laboratory of Plant Nematology is focused on the study of nematode communities of natural ecosystems and agroecosystems in Slovakia within the specific geographical area of Central Europe. Attention is paid to the taxonomy and systematics of free-living nematodes and plant-parasitic nematodes of different ecosystems and the utilization of nematodes as bioindicators of changes in the soil environment due to climatic, natural or anthropic changes. Monitoring the occurrence of new species of free-living nematodes and plant-parasitic nematodes, including quarantine species, and monitoring the possibility of introducing phytopathologically and economically important plant parasite nematodes to Slovakia in the context of global climate change. Research also involves issues of phytopathogenicity of parasitic plant nematodes and plant protection.
