Research Interests

Grazing-induced changes in soil carbon and nitrogen stocks and their mitigation potential for cattle farming and milk production
Ecosystem services of pre-alpine and alpine grassland soils with a focus on grazing-induced changes in soil nutrient stocks, dissolved nutrients, plant above- and below-ground biomass storage, as well as microbial genes
Turnover processes and matter fluxes in frozen soil and their abiotic controls (temperature, soil moisture, fire, nutrient availability)
The importance of mineral versus organic nitrogen turnover in the plant-soil-microbe system of permafrost-affected soils and feedbacks between permafrost nitrogen and climate change
Gross nitrogen turnover (stable isotope and microbiological methods) including losses of nitrous oxide in arctic peatland and dry heath soils exposed to thaw and winter warming events
Dinitrogen versus nitrous oxide losses from natural and agricultural soils

Project List:

SUSALPS: Sustainable use of alpine and pre-alpine grassland soils in a changing climate
NIFROCLIM: Soil nitrogen turnover and N₂O emissions in permafrost landscapes of Northern China in a changing climate
KUHMUS-Grazing: Reducing greenhouse gas emissions in dairy farming
