Research interests

My research mainly focus on galaxy formation using hydrodynamical simulations. I try to characterize the role of the physical mechanisms that drive galaxy formation and evolution such as merger events between galaxies (and dark matter haloes), mass accretion into dark matter haloes, the influence of feedback processes associated to star formation (e.g. UV-background, supernovae explosion) as well as black holes growth and associated active galactic nuclei (AGN) activity. I’m particularly interested in the formation of early type galaxies as well as in Milky Way type objects where I use to perform high resolution zoom simulations. On larger scales, I take an interest in developing numerical methods in order to predict the clustering statistics in the Lyman-alpha forest. Otherwise, I also like working on the Vlasov equation and phase-space structures evolutions.
