Emma Gatti is interested in Quaternary palaeo-environmental feedbacks to climatic changes . Anomalous, strong magnitude events (super-eruptions, mega-floods, earthquakes) are believed to have shaped, towards sudden climatic changes, the shape of the Earth as we know it today. I reconstruct the environmental signal as recorded in sediment sequences (lake, fluvial, eolian, volcanic) using multidisciplinary geological and geochemical techniques , from trace elements abundance to clay minerals x-ray diffraction, mass spectrometry, isotopes geochemistry, SEM, petrography and micromorphology.
