Using supernovae, strong lensing, and next-generation surveys to uniquely advance cosmology.
My work spans strongly lensed supernovae, Type Ia supernova cosmology, high-redshift transients, and the broader picture of combining multiple probes to enhance our understanding of the expansion history of the universe. I work at the intersection of JWST, Roman, and Rubin time-domain astronomy, where rare discovery, precise follow-up, and scientific infrastructure meet.
