My PhD research is about finding and dating cryptotephras in marine sediment cores around the Horn of Africa, over the last million years. The aims are : to provide a tephrostratigraphic framework, and to correlate these tephras with tuffs from the East African Rift (e.g. Silver Tuff from Konso, Ethiopia) using glass shard geochemistry. The outcomes are : the age of hominin fossils, palaeoclimatology of the area, and volcanic history of the East African Rift System.

…Magma reservoir processes.

I am interested in magmatic processes related to the initiation of continental rifting; Identifying the source and composition of hyperalkaline and carbonatitic magmas and complex deep fluids that can facilitate melting or weaken the lithosphere. Identification of the processes behind crustal thinning by combining petrogeochemistry, geophysics, and petrophysics.

Study of volcanic activity and its impact on populations in the East African Rift, in particular, numerical and analogue modelling of magma propagation in rift zones. Recent project: E-DOOR (UNESCO-IGCP) (2023-2025).
