My research work focuses on cosmological simulations in the context of data analysis for large galaxy surveys. In particular, I work on modelling galaxy clustering and weak lensing observables and their statistical properties using simulations. I am a member of the Euclid Consortium, for which I produced large galaxy mock catalogues for testing the performances of the Euclid satellite. I am part of the Exploring Dark Energy through Cosmic Structures project, for which I develop cosmological simulations of clustering dark energy scenarios.
