Research Interests

I work in the field of cosmology, using observations to test theoretical models. I focus particularly on galaxy surveys, using the positions of galaxies to measure the cosmological expansion rate and growth of cosmological structure. I use these to constrain Dark Energy, the mechanism responsible for the present-day acceleration in the expansion rate.
