Research interests
My main interest is the field of cosmology with a focus on spectroscopic galaxy surveys and how we can optimally extract information about the cosmological model with standard the two-point correlation function and non-standard statistical observables measuring the large-scale clustering of galaxies. It is in particular those non-standard observables that could help in pinning down the model for gravity on large scales. In addition, I study the theoretical description of those statistical properties and how we can improve their modelling to obtain tighter constraints on parameters hence testing the limits of the standard cosmological model. I am a member of the Euclid consortium and actively participating in the preparatory analysis for the Euclid Space telescope. Euclid will create one of the biggest maps of galaxies to unravel the origin of the accelerated expansion of the Universe via a combination of galaxy clustering and weak lensing.
