پژوهشگر ارشد
Keir K. Rogers is an STFC Ernest Rutherford Fellow at Imperial College London (starting 2025). Previously, he held the Dunlap Fellowship at the University of Toronto and a postdoctoral position at the Oskar Klein Centre for Cosmoparticle Physics, Stockholm University. He earned his PhD from University College London and a Master’s from the University of Oxford. His research focuses on cosmological model physics, leveraging statistical and machine learning techniques to analyze cosmological data. Key areas include testing ultra-light axion models of dark matter, analyzing cosmic microwave background (CMB) and large-scale structure data, and developing computational frameworks like cosmological emulators and Bayesian optimization. He contributed to bounds on dark matter models using Lyman-alpha forest data and pioneered methods for CMB component separation using wavelets. Scientific awards include the STFC Ernest Rutherford Fellowship and Dunlap Fellowship. His work involves collaborations on next-generation surveys like the Dark Energy Spectroscopic Instrument (DESI) and CMB-S4. He leads efforts to improve parameter inference through simulation-based methods and has developed tools for mitigating high-density absorber contamination in Lyman-alpha forest analyses.
