A personal statement
Most of my research is focused in the study of geodynamical processes using numerical models. My main project focuses in the feedback between volatiles and convection dynamics. The presence of water in the mantle significantly decreases its viscosity and can completely change the geodynamical evolution of the planet. I am using StagYY to develop global numerical models to study the water budget in the mantle and the thermal evolution of the Earth.
In the past I implemented three-dimensional models to study subduction processes at a regional scale using Comsol Multiphysics and CitcomS. I studied the influence of the thermal state of the overriding plate in subduction geometry, showing that slabs subduct with a lower dip beneath colder overriding lithosphere. I also studied how a slab with non-uniform dip can induce trench parallel flow in the mantle, which might have important implications for seismic anisotropy. I also investigated the implications of a non-uniform overriding plate and slab dip in subduction velocity and Euler pole parameters. I am looking forward to expanding these models including melt and fluid generation and transport. In particular, I am interested in understanding how the paths of melt and fluids are affected when the subducting slab induces a complex mantle flow, including an intense trench parallel flow and flow around the edges and gaps.
I am also also working on a project to study ductile deformation and strain localization beneath strike slip faults. For this, I am using deal.II to write a finite element software to solve the viscoelastic equations in two and three dimensions.
I have also worked and am interested in GUI development, machine learning and computer vision.
