Description of research and teaching
The focus of research is microbial ecology and microbes important for ecosystem functioning.
Some reserach lines can be distinguished: microbes in peatlands related to climate change and production of greenhouse gases, microbes in contaminated soils and their potential for degradation of hydrocarbons and changing oxidation states of heavy metals; microbes living in association to plants and their interaction with contaminants; the effect of biofertilizers on microbes in agricultural lands and on soil fertility.
Teaching deals with microbial ecology and environmental biotechnology.
