Interests

My primary research interests lie in the field of quasar formation and reionisation in the early universe. In particular I am interested in the evolution of the earliest galaxies and how this evolution may be studied with the next generation of radio telescopes. I also work in the field of gravitational lensing. Specifically, I study problems in quasar microlensing, and the statistical properties of gravitational lensing by galaxies and clusters of galaxies.
