I am a theoretical cosmologist and my interests are in the formation and evolution of galaxies, in particular in the formation of our own galaxy, the Milky Way. To this aim, I build computer simulations that follow the evolution of Milky Way-type galaxies since their birth until the present time. I am also interested in making detailed comparisons of these simulations with the observational data, for example, by analysing the distribution of stars in the Galactic halo or in the neighbouring dwarf galaxies or along various tidal streams orbiting the Milky Way.

I also have an interest in deciphering the nature of dark matter and I currently work on how we can distinguish between various possible dark matter models (e.g. cold versus warm dark matter) by using the chemical and kinematical signatures of stars in the Milky Way.
