Dr Keir Rogers is a Proleptic Senior Lecturer in Physics in the Department of Physics, King’s College London. Rogers is a theoretical cosmologist and data scientist whose work lies at the intersection of cosmology, statistical inference and machine learning. He is currently a UKRI STFC Ernest Rutherford Fellow (from 2025), which he previously held at Imperial College London. Before that, he held a Dunlap Fellowship at the University of Toronto and a postdoctoral position at the Oskar Klein Centre for Cosmoparticle Physics at Stockholm University. Rogers obtained his PhD from University College London (UCL), following a master’s degree at the University of Oxford.

He is a member of the Dark Energy Science Collaboration contributing to analysis of data from the Vera C. Rubin Observatory, as well as the Euclid, Atacama Cosmology Telescope and Simons Observatory collaborations.

Research

His research focuses on probing fundamental physics through cosmological observations, in particular exploring dark matter models such as ultra-light axions, developing robust statistical and machine learning tools for parameter inference, and applying these techniques to the cosmic microwave background (CMB), large-scale structure and the Milky Way’s substructure.

In his work, he combines theory, simulations, and data, using methods like emulators, Bayesian optimisation, simulation-based inference and wavelet decomposition to push forward constraints on dark matter and signal extraction in the CMB.
