I am a PhD student working on supernova cosmology and lensed supernova cosmography under the supervision of Kaisey Mandel and Suhail Dhawan. I am interested in using physically-motivated statistical models for Type Ia Supernovae (SNe Ia) and gravitationally lensed SNe to learn about fundamental cosmological parameters.
