    Research topic(s)

  • The main focus of my research is to develop models of mantle convection self-generating plate tectonics, using the StagYY numerical code from P. Tackley, in order to study and understand the interactions between mantle dynamics and its surface expressions on Earth. I am more particularly investigating the spatial and temporal evolution of dynamic topography in those numerical models in order to compare it with Earth observations and understand from which processes it originates. Another project is to study the dynamics of mantle plumes in 3D models of mantle convection with plate tectonics in order to understand how their interactions with the surface can cause them to move laterally. I collaborate with geologists from the EarthByte group at the University of Sydney and the University of Wollongong in Australia in order to help to improve reconstructions of the past locations of continents on Earth thanks to the physics of my models.
