Forschungsinteressen

My research aims at understanding the impact of climate variability on terrestrial environment. I am developing an approach combining isotopic geochemistry and dating on biogenic and pedogenic carbonates from aeolian sequences. I am particularly interested in reconstructing palaeoclimate data during the Quaternary by using the stable isotopic composition of original proxies such as earthworm calcite granules. I am also focusing on longer time scale to characterise the impact of climate variability on Central Asian loess-palaeosol sequences and to explore the response of Central Asian land surfaces to climate dynamics, which could have generated terrestrial feedbacks affecting atmospheric and ocean circulation. I have been involved in projects in western and central Europe and Central Asia.
