Marie Skłodowska-Curie PhD Fellow
My primary research interest is the initial development of soil ecosystem in recently deglaciated ecosystems of Polar and Alpine regions. Using a chronosequence approach, I investigate the concurrent changes in microbial community development, nutrient build-up as well as weathering-induced changes in geochemistry and mineralogy that lead to soil formation. Complementarily, I examine the pedological variability that arises from geomorphological heterogeneities in glacier forefields. I also investigate the role of aeolian pathways in supplying nutrients stocks and potential microbial colonizers in these terrains and monitor its seasonal biogeochemical variability.
Besides, I study the positive feedback effect of Arctic permafrost thaw on global warming via the remobilization of previously frozen organic matter. Specifically, I have experience in assessing upscaling tools to evaluate the total storage, landscape distribution and vertical partitioning of soil organic carbon (SOC) in High-Arctic regions.
