In the first part of my talk I will present results from a set of high resolution cosmological simulations focusing on the formation of the first galaxies in the Universe. I will discuss the impact of the baryons on the hosting dark matter haloes as well as the physical processes that drive the evolution of these galaxies. In the second part of my talk I will introduce a methodology to extract effective models from such simulations to break the degeneracy of sub-grid physical models in cosmological simulations.
