My work is at the intersection between theoretical and observational cosmology, with an emphasis on modelling and constraining dark energy, modified gravity, neutrino properties, non-Gaussianity, and other cosmological components - as well as methods for testing fundamental assumptions in the concordance model of cosmology. In this context, I employ state-of-the-art statistical and numerical methods to analyze data and forecast future experimental capabilities from surveys of cosmological expansion and growth of structure. Recent work includes predictions for tests of modified gravity models with voids, a popular account of which can be found here.
Some of my work focuses on using galaxy clusters and voids as cosmological probes, especially as a member of the Euclid Consortium, XMM Cluster Survey (XCS) and the XXL Project.
