Antony Lewis

I am Professor of Cosmology at the University of Sussex, working on various aspects of cosmology, particularly the Cosmic Microwave Background (CMB) and its gravitational lensing. I was part of the core team analyzing data from the Planck satellite and am currently part of the Simons Observatory collaboration.
