My research focuses on understanding how changes in environmental conditions and management affect the carbon and greenhouse gas exchanges of peatland ecosystems.


The main goal of my current research is to improve our understanding of how the individual component fluxes of the peatland carbon (C) cycle (i.e. gross and net primary production, heterotrophic and autotrophic respiration as well as plant-mediated CH4 transport) respond to their biotic and abiotic drivers. More specifically, I am interested in exploring the relationship between vegetation development and the relative contribution of these component fluxes during distinct phenological phases. To address these objectives, I use an automated chamber system for quantifying CO2 and CH4 fluxes, monitor a suit of environmental variables and collect biotic data from phenology cameras (canopy greenness index) and spectral sensors (NDVI and PRI) in a boreal nutrient poor minerogenic mire Degerö Stormyr.
