text: Meibom currently leads the laboratory for biological geochemistry at EPFL. Research performed in his laboratory is interdisciplinary in nature, at the interface between isotope geochemistry and biology. Active themes in the laboratory include the use of NanoSIMS to visualize and characterize the diagenesis of biogenic substrates, as well as the study of metabolic processes in symbiotic organisms (notably corals) and how these processes may be influenced by environmental stress, in particular climate change.
