About me

I am a postdoctoral research fellow at Leiden Observatory, supported by an NWO Veni grant and previously by an EU Marie Skłodowska-Curie Individual Fellowship.

My main research interest is to find out how galaxies connect with the Universe around them: how are they accreting new gas, which ultimately fuels their star formation? And how can matter be ejected from galaxies back into their environment? I try to answer these questions by studying, in particular, galaxies that live with hundreds or even thousands of others in the dense environment of galaxy groups and clusters.

My main tool for this research are cosmological hydrodynamic simulation, in particular the Hydrangea/C-EAGLE suite of galaxy cluster simulations of which I am the PI. I am also closely involved in the production of two next-generation simulation projects, "Eagle-XL" and "COLIBRE".


At Leiden Observatory, I am a member of the Galaxy Formation group led by Joop Schaye and the Observational Cosmology group of Henk Hoekstra. I am also a member of the Virgo Consortium as well as several observational surveys including BUFFALO, Euclid, and Vertico.
