I am a geodynamicist focusing on early Earth dynamics, 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. My work  bridges the gap between geodynamics and seismology to better understand the global pattern of mantle flow, especially in the lowermost mantle. I utilize advanced tools such as the ASPECT mantle convection code to model time-dependent flow fields, along with the ECOMAN software suite to simulate mantle fabric dynamics.
