At the beginning of my PhD, I worked extensively on the formation and evolution of galaxies and their baryonic environment using state-of-the-art hydrodynamical simulations.

My research focus has since shifted to understanding the fate of the smallest bound dark matter structures in the universe. I use advanced mathematical techniques to model the orbital dynamics of systems with dynamical mass ranges spanning over twelve orders of magnitude.
