My research focuses on constraining the dynamics and geochemistry of the lithosphere through time. Current research topics are: 1) timing and duration of petrological processes; 2) formation and differentiation of the early continental crust; 3) processes of continental collision and exhumation; 4) controlling factors and novel applications in chronology (Lu-Hf, U-Pb, Sm-Nd); 5) feedbacks among reactive fluid flow, phase changes and deformation in subducted crust.
