Alessandra Mazzoli - Research Interests and Education
Nitrogen (N) is one of the most abundant elements on Earth and can be found in several forms in different environments (biota, aquatic ecosystems, sediments, atmosphere and soils), which are interlinked through the N cycle. This is the most bioenergetically advanced biogeochemical cycle on Earth and is now receiving growing attention in view of its role in climate change (greenhouse gas N2O) and environmental deterioration (eutrophication). Thus, understanding the fluxes and controlling factors within this cycle is of crucial importance in light of the current circumstances.
During my PhD I will investigate the fate of fixed nitrogen in lacustrine and marine surface sediments using the characterized isotopic fractionation of nitrate-consuming processes (denitrification, anammox, DNRA). By combining porewater analysis and trace experiments I hope to better understand the environmental and chemical constraints on such processes and their relative contribution in different settings.
This investigation will benefit from the combined efforts of Tim Paulus and myself to tackle a common research aim using complementary experimental approaches.
