I graduated in Physics from Universitat Autònoma de Barcelona (UAB) in 2012 and completed a master in Modelling for Science and Engineering in 2014. During my master studies, I was working as a technician to support the research in the Radiations department at UAB with the Research Group of Ionizing Radiations (GRRI). I was mainly involved on nuclear track detectors and simulating neutron processes and interactions with MCNPX code. I also partcipated in several irradiation campaigns with Bonner Spheres and CR-39 detectors in facilities in Sevilla and Rome. 

In December 2020 I defended my PhD thesis in numerical methods at Universitat Politècnica de Catalunya (UPC). My thesis, “Advanced numerical techniques for geophysical inverse problems”, combines Model Order Reduction techniques with probabilistic inverse problems to drastically reduce the high computational cost of the large number of required forward evaluations without losing accuracy in the inversion results. In particular, the methodology proposed is applied to an inversion example to infer the Earth's lithospheric structure from dynamic topography data generated due to the sublithospheric mantle flow.

Since February 2021 I am working as a postdoc in the the Fusion Group at BSC within the FusionCat project to further develop the capabilities of the neutron transport module integrated in the multi-physics simulation code Alya.
