Research Interests


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

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

  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. measuring the baryon budget of clusters and groups of galaxies and the efficiency of star formation in different environments

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

  5. detailing the transformation of spirals into early-type galaxies via galaxy-galaxy interactions and mergers

Some details are in my TED talk here:
