My research focuses on galaxy formation and active galactic nuclei (AGN). As part of the SKIRT team, I developed a non-local thermodynamic radiative transfer module within the state-of-the-art radiative transfer code SKIRT. Additionally, I model grain size evolution and a non-equilibrium chemical network alongside hydrodynamic simulations. I explore dust, molecular, and atomic emissions from the interstellar medium by generating synthetic observations from these hydrodynamic simulations with SKIRT. These simulations allow me to interpret observational data of galaxies and AGN captured by ALMA and JWST and refine physical models incorporated in hydrodynamic simulations.
