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.

Setting the course for research

Connected to the world and involved in their community, the astrophysics research teams are paving the way to greater knowledge of our universe. 

It all starts with our researchers

Our researchers specialize in exoplanetary, solar, stellar and extragalactic astronomy, in addition to developing leading-edge instruments.
