My research is theoretical, and my principal interests include black holes, cosmology, and supernovae. My black hole work focuses on general relativistic visualization. My cosmological work concentrates mainly on devising and applying methods to analyze large observational data sets, notably galaxy surveys, with a view to extracting cosmological parameters and other fundamental properties of the Universe.
