Exoplanet hunter


René Doyon heads up the Institute for Research on Exoplanets (iREx) and is the director of the Mont-Mégantic Observatory. He designs observation programs and develops leading-edge instruments, in particular the NIRISS, which the James Webb Space Telescope will be equipped with. His team was the world’s first to directly observe the existence of planets around stars other than the Sun.
