Richard is a Hintze Prize Fellow in Astrophysics (Cosmology). He is a member of the Aquila Consortium, Learning the Universe, and CAMELS collaborations. His research centres on Bayesian forward modelling of astrophysical observations and digital twins of the local Universe. He works principally on two fronts: initial-condition inference of the Universe with BORG, reconstructing the cosmic web from galaxy clustering and peculiar velocities; and Bayesian hierarchical models of the distance ladder, aimed at measuring the Hubble constant in light of the Hubble tension.
More broadly, he is interested in galaxy formation and semi-analytic modelling, cosmological rescaling techniques, forward modelling of the cosmic microwave background, and applications of machine learning in astrophysics and cosmology. He completed his DPhil at Oxford under the supervision of Harry Desmond, Julien Devriendt, and Adrianne Slyz.
