The main research interest of Katja are marine biogeochemistry and in particular how microorganisms can drive the different elemental cycles. She did her PhD in the Geomicrobiology group of Prof. Kappler at the Eberhard Karls University in Tuebingen, Germany in collaboration with the Center for Geomicrobiology in Aarhus. She studied microbial iron cycling in coastal marine sediments from Aarhus Bay, focusing on the abundances and the activity of the different types of Fe(II)-oxidizers and Fe(III)-reducers.

The focus of Katja’s work at the Center will be on the competition between microbial Fe(III) and sulfate reduction in Artic sediments. Therefore, incubation experiments with sediment for rate measurements of the different microbial processes will be done. These experiments will include inhibition experiments, in order to separate the different biotic and abiotic processes, as well as the manipulation of various parameters, like organic carbon or iron content, to determine which parameters control the competition.
