Didier Queloz

Prof Didier Queloz is a Professor at the Cavendish Laboratory, University of Cambridge, specializing in astrophysics with a focus on exoplanet research. His work involves observational studies using advanced instruments like CHEOPS and TESS to characterize exoplanet systems. He leads research on planetary systems, including studies of orbital dynamics, atmospheric properties, and planetary formation mechanisms. His recent work emphasizes the discovery and analysis of transiting exoplanets, brown dwarfs, and substellar companions.

Key research themes include exoplanet atmospheres, transit timing variations, and the interplay between planet-star interactions. Prof Queloz's projects leverage multi-wavelength observations to explore topics such as nodal precession in hot Jupiter systems and the climate of ultra-short-period planets. His contributions to instrumental development, such as CHEOPS, underscore his role in advancing exoplanet detection and characterization techniques.

Recent publications highlight discoveries like the eccentric WASP-18 b system, resonant mini-Neptunes in TOI-1803, and the architecture of TOI-561. These studies reflect his expertise in combining photometric and spectroscopic data to unravel planetary system dynamics. His work also addresses fundamental questions about planetary formation, habitability, and the evolution of exoplanetary atmospheres.

Prof Queloz is affiliated with the Department of Physics at the University of Cambridge and collaborates with international teams through initiatives like the SPECULOOS project. His research outputs are disseminated through peer-reviewed journals and public data catalogs, contributing to the global astrophysics community.
