Current research interests

My research largely focuses on the alteration of the oceanic lithosphere. In particular, I investigate fluid-rock interaction processes and the fundamental links between mineral reactions and biogenic activity, and how the chemical interaction between the geosphere, hydrosphere and biosphere impacts the global geochemical cycles. As oceanic lithosphere is altered various species, including H2O, S, C, Ca, and Mg, are transferred from the fluid into the rock. During subduction, dehydration reactions release and transport these species into the overlying mantle wedge. The aim of my research is to investigate the chemical and petrophysical changes during rock alteration and to evaluate the links between abiogenic and biogenic processes. This includes the study of water-rock interaction mechanisms, the controls on reaction rates and kinetics, and how mineral alteration reactions facilitate biogenic activity that may enhance, e.g., S and C storage. In addition, I investigate how these processes impact large-scale geochemical cycles. Particularly how effective this altered lithosphere is as a transport medium for inorganic and organic compounds, volatiles such as CO2 and H2O, and sulfides and metals into the mantle and how e.g., sulfur is released during metamorphism of the subducted oceanic lithosphere. In my research I use traditional and novel stable isotope systems (e.g., S, C, O, Ca) in combination with bulk rock and high-resolution in situ techniques (secondary ion mass spectrometry), μ-XANES, bulk rock major and trace element signatures, radiogenic isotopes (e.g., 87Sr/86Sr), mineralogy and petrology (electron microprobe analyses, scanning electron microscopy, X-ray diffraction, optical microscopy).
