I am a postdoc at DAWN working on unveiling the relation between galaxies and their dark matter halos throughout cosmic history since the epoch of reionization. To this end I am part of several JWST programs, most notably COSMOS-Web and FRESCO, in which I build multi-band, model-fitting catalogs from the infrared to the optical. Such multi-band catalogs in some of the largest JWST-observed areas allow efficient detection and characterization of extreme populations of massive, quiescent and high redshift galaxies. These observations promise to unveil their growth in relation to the dark matter environment throughout cosmic history.
