I'm a third-year PhD student at the Hamburg Observatory and part of the excellence cluster Quantum Universe. My research interests are astrophysics on large-scales and models beyond ΛCDM. I prefer to work numerically, including all the way from new ideas for numerical schemes to the analysis of simulation data.
In my PhD project, I focus on the phenomenology of dark matter with frequent self-interactions (small-angle scattering). N-body simulations are employed to study how self-interactions can alter the distribution of dark matter. In particular, I have developed a numerical scheme that allows – for the first time – to simulate mergers or do cosmological simulations with this type of self-interaction. For more details, see my publications.
