My research focuses on strong gravitational lens modeling in the context of time-delay cosmography, with the goal of constraining the Hubble constant. I am particularly interested in developing and applying advanced modeling techniques for high-resolution imaging data, as used within the TDCOSMO collaboration. Before starting my PhD, I completed my Bachelor's and Master's studies in Physics at ETH Zurich, where my Master's thesis explored 21 cm cosmology and the use of artificial intelligence, specifically normalizing flow models, to identify and characterize ionized regions (H II bubbles) in the early Universe.
