At the end of my undergraduate studies in geography at the University of Freiburg, I visited The University of Auckland for three months where I worked on the vulnerability of freshwater resources of small Pacific islands. My research focus shifted to northern ecosystems during my graduate studies at the University of Goettingen and the Universitaet Hamburg. I investigated the influence of permafrost and seasonal thaw dynamics on the plot- and catchment-scale hydrology of polygonal tundra ecosystems.
My research helped to better understand the vertical fluxes of CO2 and CH4 and the lateral fluxes of dissolved organic carbon and nutrients that are closely linked to hydrological conditions in these ecosystems. Since January 2013, I am working on greenhouse gas and energy fluxes between permafrost-affected ecosystems and the atmosphere. For my PhD project, I am coupling eddy covariance flux measurements to footprint models and remote sensing data to better understand the effect of permafrost degradation and related land cover changes on the atmosphere-ecosystem exchanges of greenhouse gases and energy.
