Main Research Fields
Galaxy clusters trace the extreme peaks in the matter density field of the early Universe. Measuring their number density and clustering as a function of mass and cosmic time can not only tell us about the structures themselves, but also the physical laws that govern our Universe on the smallest and largest scales.
My research on galaxy clusters and their constituent galaxies is driven by open questions in cosmology and galaxy evolution such as: when did the largest gravitationally bound structures in the cosmic web, galaxy clusters, form and how have they evolved over cosmic time? What physical mechanisms drive the galaxies that reside in these giant structures to stop forming stars? I harness numerical simulations to support observational measurements. I then use observational measurements to inform and develop our theoretical understanding of these massive structures.
