Rebecca Chen: Type Ia Supernova Cosmology from DES to LSST and Roman

In this talk, I will detail some of the key analysis improvements from the final DES supernova analysis comprised of ~1600 photometrically classified SNe which have allowed us to make the best SNIa constraints on the dark energy equation of state parameter to date. I will discuss how these developments are informing current efforts underway in preparation for the next generation of surveys for supernova cosmology, specifically with Rubin LSST and the Roman Space Telescope.
