I'm a computational cosmologist working on modelling and constraining the effect of massive neutrinos on the Large-Scale Structure of the Universe. To this purpose I use a combination of tools, including N-body simulations, perturbative bias expansions, and Bayesian analysis. To make this efficient, I use neural networks to predict key quantities such as the matter power spectrum or nonlinear galaxy clustering.
