I am primarily interested in studying the astrophysical processes that govern galaxy formation and evolution. In the past years, I tackled several questions on this subject and investigated nearby dwarf galaxies by means of ground-based and space-based observations. Additionally, I am interested in developments in observational astronomy, data-driven astronomy and applications of state-of-the-art machine learning techniques for astronomical research.
