My main research interest is the structural and functional characterization of soil bacterial, archaeal, and fungal communities in different biotopes influenced by biotic and abiotic environmental factors. To achieve these goals, I use genetics-based approaches (e.g., sequencing, qPCR of taxonomic and functional marker genes) and combine them with measurements of soil processes (e.g., enzyme activities, respiration, methanogenesis, denitrification). I am currently interested in carbon and nitrogen cycling in Arctic permafrost soils in relation to soil microbial communities and greenhouse gas emissions.
