Research
My research interests encompass a broad range of topics from the
content and structure of our own Galaxy's halo through to the
detection of the most distant known quasars. A common theme is the
development of new statistical analysis techniques which are then
applied to very large data sets to study object populations of current
theoretical interest in astrophysics.
Much of my recent research has employed spectra from the Sloan Digital
Sky Survey (SDSS) database. Current projects include the use of
intervening absorption lines in quasars to provide a more complete
understanding of galaxy evolution by understanding how gaseous
material surrounding galaxies is related to the star formation
histories and global properties of galaxies. Developing a better
understanding of quasar outflows and how feedback associated with the
presence of central massive black holes influences the evolution of
galaxies is another topic of interest.
In the Institute of Astronomy I enjoy making contributions to the research activity that extend from Near Field Cosmology through to studies of galaxies and quasars close to the epoch of reionisation.
