Staff profile

I am a geodynamicist focusing on early Earth evolution, evolution of mantle plumes, dynamics of thermochemical piles and deep earth seismic anisotropy. My PhD thesis was about investigating the shear wave seismic anisotropy development due to plume generation from Large Low Shear Velocity Provinces.
