My research focuses on the development and application of models that are designed to advance our understanding of the global biogeochemical dynamics and elucidate the environmental controls on past, present and future carbon cycling and climate. I am especially interested in the diagenetic transformations and burial of carbon in marine sediments on different spatial and temporal scales and its impact on global biogeochemical cycles and climate. In addition, I am also interested in the biogeochemical dynamics of the land-ocean continuum and the influence of the estuarine filter on carbon and nutrient fluxes.
