Biography

I am freshwater ecologist currently working as a PostDoc researcher at the Ecology and Genetics research Unit. My research interests focus on microbial ecology of freshwater and soil, particularly in those affected by land use and/or high concentrations of contaminants such as nutrients, metals and metalloids. I’m especially interested in the community-level changes of microbes under anthropogenic pressure using modern molecular techniques. Also, plant-microbe interactions of species adapted to contaminated i.e. extreme environments and the role of their symbiotic microbes in accumulating contaminants is an interesting field of research. Bioremediation potential of arctic microbes and plants, as well as their combinations, are studied in two ongoing projects: HybArkt and the moss Warnstorfia fluitans and its microbial symbionts for phytoremediation of mining and municipal wastewaters.
