About
Michaël Gillon is a Belgian astrophysicist whose work has fundamentally reshaped the search for habitable worlds beyond our solar system, with a particular focus on exoplanet detection around ultracool dwarf stars and brown dwarfs. Best known as the driving force behind the TRAPPIST telescope project — a 60-cm robotic instrument at ESO's La Silla Observatory — Gillon pioneered a systematic observational strategy targeting the smallest, nearest stars where temperate, Earth-sized planets are most detectable. These efforts laid the groundwork for his landmark discovery of the TRAPPIST-1 planetary system, widely celebrated as one of the most significant finds in modern astronomy. Building on this foundation, Gillon spearheaded the ambitious SPECULOOS network — a suite of 1-metre robotic telescopes spanning both hemispheres — designed to survey approximately 1,000 ultracool dwarfs for transiting rocky planets amenable to atmospheric characterization with next-generation observatories. His most cited works, collectively accumulating over 700 citations, reflect sustained influence across exoplanet instrumentation, survey design, and brown dwarf characterization. His research has positioned ultracool dwarfs as premier targets in humanity's ongoing search for potentially life-bearing worlds.
