Research group: Geochemistry and Pollution
Within the Anthropocene new epoch, the consequences of environmental oscillations at time scales relevant to human life and societal development are as yet to be explored. My research interest lies in setting boundaries to possible causes of changes occurring when thresholds are crossed in the Earth’s system: involving the temporal and spatial distribution of insolation, volcanic activity, wind patterns, ocean’s thermohaline pump, extension and retreat of marine and continental ice and the chemistry of the atmosphere. The Arctic, North Atlantic and Mediterranean regions are taken as the laboratory for tracing these processes and the tools for detecting them are fossil organic compounds originally forming part of diverse organisms, such as bacteria, archaea or eucarya (e.g. marine and terrestrial flora). The study of how transition phenomena occur in the past and present will place events to come in their proper context.
