Richard Ellis is an observational cosmologist who studies galaxy formation and large scale structure.
He uses a variety of observational facilities to trace the distribution of dark matter over a wide range of scales, and to explore the earliest galaxies which are thought to have ionized the universe. Ellis takes a special interest in gravitational lensing, or how matter’s gravitational field can bend light on its path between a source and an observer. He is leading an international effort to build an instrument that will trace the growth of structures directly from patterns in the large-scale distribution of faint galaxies, and is currently using the Hubble Space Telescope and large ground-based telescopes to characterize the properties of the most distant galaxies.
