My work revolves around the study of galaxy clusters and their constituents: dark matter, the intra-cluster medium, and galaxies. I am primarily interested in the most massive clusters in the Universe and have specialized in finding these rare objects through their X-ray emission. Giant clusters offer spectacular opportunities to investigate a huge range of extragalactic science, from violent galaxy evolution by ram-pressure stripping, through the dynamics of dark-matter collisions, to the properties of the first generation of galaxies, revealed by gravitational lensing.
I am a heavy user of 8m-class telescopes on Maunakea, HST, and the Chandra X-ray Observatory.
Other interests of mine include teaching (high-school to graduate level) and long-distance running.
I am the Principal Investigator of several ongoing projects, all involving both giant galaxy clusters and lots of collaborators from around the globe.
