Research Interests:

Nature and evolution of hot gas in galaxies & clusters of galaxies. Recent studies include: constraining Type Ia supernovae models with X-ray spectroscopy of intracluster gas investigating the origin and energetics of high-redshift Lyman-alpha clouds constructing and analyzing the first X-ray-complete sample of elliptical galaxies using the energy content and chemistry of cluster gas to constrain the nature of galaxy formation discovering that abundance gradients in the hot gas of galaxy clusters are common determining the dynamical temperature of dark matter in elliptical galaxies assessing environmental influences on the X-ray emitting gas in early-type galaxies using partially overlapping galaxies to determine directly the opacity of spiral galaxies
