Erin Hayes

Research

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