Scientific interests

During sea-going expeditions, I am studying the input of water, methane and other volatiles into the ocean through cold seeps and mud volcanoes, the formation and dissociation of marine gas hydrates, the microbial degradation of sedimentary organic matter and the recycling of nutrients into the ocean. Moreover, I am evaluating and reconstructing the geochemical evolution of the oceans and the atmosphere using proxy records from marine carbonates and evaporite. I am using numerical models to simulate long-term changes in the earth system with a special focus on biogeochemical processes in marine sediments.
