I am interested in galaxy formation theory, in particular the interface between galaxies and their supermassive black holes. To this end, I develop new galaxy formation models and perform hydrodynamical simulations of individual galaxies as well as representative regions of the Universe with the moving mesh code AREPO.

During my PhD, I investigated the hitherto unexplored role of black hole feedback from active galactic nuclei (AGN) in dwarf galaxies. My current research focus is to build novel models of black hole evolution (including black hole formation, growth, and feedback) for galaxy formation simulations, which take advantage of the superior resolution and allow for detailed multimessenger predictions in preparation for the next-generation electromagnetic and gravitational-wave observatories.
