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 non-concordance and modified-gravity models with voids.
Some of my work focuses on using galaxy clusters and voids as cosmological probes, especially as a member of the Euclid Consortium, the Square Kilometre Array working groups, 4MOST, the XMM Cluster Survey (XCS) and the XXL Project.
