Academic Interests:

My research focuses on various aspects of mantle convection, especially on dynamics of mantle upwellings in the form of plumes. I use numerical methods, in particular the open-source finite element code ASPECT, to simulate the behavior and evolution of mantle plumes from their origin at the core-mantle boundary (CMB), to their interaction with tectonic plates at the surface. As part of this work, I am also interested in the deformation of the CMB as response to mantle flow, the processes that determine the style of large-scale mantle convection, and melt generation and migration at the surface that leads to volcanism. Due to my background in seismology, I aim to combine geodynamic models with observations from seismology, geochemistry, mineral physics, and other geophysical observables.
