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 (see this page: https://www.astro.ljmu.ac.uk/Artemis).
I am particularly interested in making detailed comparisons between cosmological simulations of the Milky Way and the most up-to-date observational data in our Galaxy, for example, the data obtained from the Gaia satellite. Examples of my recent work include modelling of stellar haloes of Milky Way-type galaxies and of satellite dwarf galaxies orbiting these systems.
I also have an interest in deciphering the nature of dark matter and, to this aim, I develop models that help us distinguish between various possible dark matter particle candidates using cosmological simulations.
