Paul Alexander

Prof Paul Alexander is a Professor at the University of Cambridge's Department of Physics, affiliated with the Battcock Centre for Astrophysics and the Cavendish Laboratory. His research focuses on observational cosmology, particularly the Epoch of Reionization (EoR) and the early Universe's evolution. He leads projects like the Hydrogen Epoch of Reionization Array (HERA) and the REACH radiometer, advancing radio astronomy instrumentation and data analysis techniques.

His work integrates cutting-edge observational methods with computational models to study cosmic evolution. Recent efforts include developing Bayesian analysis tools (e.g., TempoNest) and visibility simulators (matvis) to optimize interferometric data processing.

Key contributions span 21-cm signal detection, instrument calibration, and interdisciplinary collaborations in astrophysics. His research bridges cosmology, radio astronomy, and computational methods, with applications to understanding the Universe's earliest phases.
