Reis Tyson

Profile

MPhys graduate specialising in observational cosmology, statistical methods and astrophysical theory.

My research focuses primarily on Type Ia supernova standardisation for improved cosmology, with broader interests in astrophysics, statistical inference, general relativity, cosmological inflation and theoretical models of the Universe.

Research Experience

Principal Component Analysis of Type Ia Supernova Spectra

MPhys Research Project

Investigating whether principal component analysis can improve Type Ia supernova standardisation by incorporating spectral information beyond SALT2. The project explores spectral reconstruction, dimensionality reduction, twinning and improved cosmological distance estimation.
