I am a cosmologist and astrophysicist, in the Department of Physics at Imperial College London, where I am also the Director of the Imperial Centre for Inference and Cosmology. I am especially interested in the interpretation and analysis of cosmological data using principled Bayesian statistical techniques.

I have written a book, The Random Universe: How Models and Probability Help Us Make Sense of the Cosmos, due out in November 2025 from Yale University Press! You can preorder it, ideally from your favourite local bookseller, already.

I also occasionally express my opinions on music, politics, parenthood, or technology.
