Doctoral Position in Biogeochemistry/Isotope Geochemistry Including Radiocarbon
The PhD project will focus on characterizing microbial communities and their role in carbon cycling in permafrost soils in a warmer and weather Arctic. This includes microbial activity measurements and the use of carbon isotopes (¹³C, ¹?C) to quantify carbon uptake, respiration, and sources of CO2 emissions. A further focus is on assessing how enhanced plant-derived carbon inputs and mineral-associated carbon stabilization influence microbial processes. The work will be carried out in close cooperation with national and international partners.The position will be based in the Institute of Geology and Mineralogy in the Organic Geochemistry & Radiocarbon group.
