Research Interests


My research is principally in extragalactic astronomy and observational cosmology, including

  1. using strong gravitational lenses to detect the most distant galaxies and the earliest stars, measure the expansion rate of the Universe, and constrain the properties of dark matter halos

  2. exploring the formation of galaxies and large-scale structure via the simulation and detection of Lyman-alpha emitting sources in the early Universe

  3. making an inventory of the stellar and gaseous baryons in clusters and groups of galaxies to compare to the baryon budget of the Universe and to measure the efficiency of star formation in different environments

  4. surveying galaxies across environments and redshift to isolate those factors most important in driving galaxy evolution

  5. detailing the transformation of spirals into early-type galaxies via the post-starburst, post-merger phase of galaxy evolution
