Galaxies are complex and fascinating objects -- found in various shapes and sizes -- which trace the underlying matter distribution of the Universe. Understanding how they acquire the properties they have today, i.e. deciphering how they form and evolve, is a fundamental question of modern astrophysics. At early epochs, their formation and evolution is dominated by rapid gas accretion, mergers and interactions. Later on, however, mergers and interactions become less frequent, and it is mostly slow, internal, or so-called "secular" processes, which drive their evolution. My research focuses on this late-time evolution of spiral galaxies (with an emphasis on our own galaxy, the Milky Way) and on understanding the dynamical processes that rearrange their stars and gas, while also determining their dark matter content.
