Stefan Bertilsson
Professor in ´Functional Ecology of Freshwatersand Director of the Swedish Infrastructure for Ecosystem Science (SITES). Field of research: (i) Aquatic Microbial Ecology, (ii) Biogeochemistry, (iii) Environmental Genomics and single cell methodology. Ongoing research projects on microbial transformation and cycling of Carbon, Nitrogen, Mercury and associated elements in freshwaters, oceans, and the deep terrestrial biosphere.

Research

My research focus on the role of microorganisms in nature and foremost their ability to transform and redistribute central elements (e.g. carbon, nitrogen, mercury). In my research group we rely on a combination of molecular (DNA and RNA-based) methods, isotope tracers and analytical chemical tools to understand processes such as nitrogen fixation, autotrophic carbon fixation, mercury methylation (and demethylation) and degradation of biopolymers and organic pollutants. We also study predation, symbiosis and other interactions between microorganisms (microbial ecology) and their evolution. We work both exprimentally in the laboratory and in the field (lakes, oceans) and study microorganisms in more exotic environments such as polar ecosystems and the deep terrestrial biosphere.
