Research interests

My primary research interests lie in numerical methods and its application to solve geological problems, including plate tectonics, lithospheric and mantle dynamics and rock deformation. The multi-scale and multi-physics character of the Earth interior pose a challenge for current numerical tools and provide the perfect framework for the development and testing of numerical strategies.
