Research Interests

My current research deals with the analyses of stable isotopes of dissolved oxygen and its application to biogeochemical and biotechnological issues. The studies mainly focus on surface waters, shallow groundwater and their interference in hyporheic and riparian zones. The objective of these investigations is to reveal oxygen sinks and sources, basic processes and related links to hydrological parameters. The combination with stable isotopes of DIC - dissolved inorganic carbon, DOC - dissolved organic carbon and POC - particulate organic carbon and its concentrations provide further information for the calculation of metabolic rates in order to get a better understanding of the ecosystem.

Current Projects
