Multi-field inflation: I study the production of non-Gaussiannity in two-field inflation with analytical predictions and numerical simulations. The main purpose is to constrain inflation models using observational results (mainly from the Planck collaboration).
CMB data analysis: I use Planck data to constrain non-Gaussianity from different sources which have an impact on the measurements of primordial non-Gaussianity generated during inflation.
