Teresa Einzmann - Research Interests and Education
Nitrous oxide (N2O) is a powerful greenhouse gas and a major ozone destroying agent in the stratosphere. Atmospheric N2O concentrations have increased significantly over the last few decades, which can mostly be attributed to the expanding use of agricultural nitrogen (N) fertilizers. Lakes in urbanized and cultivated areas often receive high N loadings and therefore constitute important sites of N cycling. The processes producing and consuming N2O in freshwater lakes vary spatially as well as temporarily and the biogeochemical factors controlling N2O dynamics are still poorly constrained.
In my PhD project, I will investigate the biogeochemical controls on N2O cycling in Lake Lugano, a eutrophic lake located at the Swiss-Italian border, applying stable isotope techniques including isotope tracer experiments, and analysing microbial community compositions. My research aims to characterize the mechanisms underlying N2O production and consumption as well as the effects of changing environmental conditions (O2, nutrient availability) on these processes.
