Astrostatistics

Cosmology is all about the broad-brush average behaviour of our Universe, and our models are typically constrained using huge data sets compressed down into a few summary statistical quantities. Moreover, since we can only observe one sky, understanding the underlying distribution from which our data are drawn is essential to interpreting astronomical observations. Advanced statistical methods therefore make up a key part of the cosmologist’s toolbox.

I have worked extensively on developing new techniques to solve statistical problems in cosmology, with a particular focus on surveys of large-scale structure as traced by galaxies and weak lensing fluctuations. I am interested in Bayesian methods and how likelihood functions should be used to allow surveys to obtain precise and accurate information about our Universe.
