Our group is involved in several area of research in cosmology. The bulk of the activity is dedicated to the study of the cosmic structure formation as a mean to investigate the nature of the invisible components in the universe such as Dark Energy and Dark Matter. Our approach make use of both analytical and numerical methods for the identification of novel cosmological observables.

A veritable team effort is devoted to the realization of large volume high-resolution numerical simulations. Our group is one of the main users of super-computing facilities in France and Europe with access to tier-1 and tier-0 machine.

The group also participates to the science support and simulation working group of two observational projects:
