About
Didier Queloz is a leading figure in observational exoplanet science, renowned for his pioneering work in the detection and characterization of planets orbiting ultracool dwarf stars and brown dwarfs. Best known for co-discovering the first exoplanet around a Sun-like star — work that earned the 2019 Nobel Prize in Physics — Queloz has since driven the development of innovative robotic telescope networks designed to uncover potentially habitable worlds. His leadership in the TRAPPIST project (138 citations) laid the groundwork for the landmark discovery of the TRAPPIST-1 planetary system, while his stewardship of the SPECULOOS network (105 and 76 citations) represents a bold next-generation effort targeting roughly 1,200 ultracool dwarfs for Earth-sized, potentially life-bearing planets. His contributions extend to precision radial velocity instrumentation through the HARPS3 project and wide-field transit surveys via NGTS, demonstrating a remarkable breadth across both hardware and observational strategy. Notable additional work includes the photometric monitoring of the nearby brown dwarf binary WISE J104915.57 (76 citations), revealing rapid atmospheric variability. Together, Queloz's research portfolio reflects a sustained, systematic commitment to answering one of science's most profound questions: are we alone?
