Olivier Hernandez, Director of the Planetarium, is an astrophysicist with expertise in instrumentation, specializing in galaxies and exoplanets.
He earned his engineering degree from the École centrale de Marseille and his master’s degree in physics from the Université de Montréal. He also holds a PhD in astrophysics, with a thesis conducted jointly between the Université de Montréal and the Astrophysics Laboratory of Marseille, focusing on galaxy dynamics.
A co-founder and former coordinator of iREx, he has also served as Director of Operations for the Observatoire du Mont-Mégantic (OMM). This observatory features a 1.6-metre telescope and is home to a nationally and internationally renowned experimental astrophysics research centre. Additionally, he has been a lecturer in the Department of Physics at the Université de Montréal.
His primary research interests include the kinematics and dynamics of barred spiral galaxies, particularly the study of the distribution of visible and non-visible matter. He also contributes to the development of advanced astronomical instrumentation, specializing in both the study of galaxies and the detection and characterization of exoplanets.
As a project director at OMM, Olivier coordinated international projects such as SPIRou and NIRPS from Montréal. These instruments aim to detect Earth-sized planets by 2021. He also played a key role as Montréal coordinator for the development and construction of one of the four scientific instruments for the successor to the Hubble Space Telescope: the James Webb Space Telescope (JWST). The Canadian JWST instrument, led by Professor René Doyon from the Université de Montréal, enables the detection and chemical composition analysis of exoplanet atmospheres, including the potential presence of water and other markers of biological activity such as oxygen and methane.
In addition, Olivier coordinated a team of researchers, engineers, and technicians managing and developing all astronomical instrumentation for the Observatoire du Mont-Mégantic, with funding from the Canada Foundation for Innovation (CFI) in 2009.
Currently the Director of the Planetarium, he is also responsible for research and ecological transition initiatives and is the founder of the Equity, Diversity, and Inclusion Committee at Espace pour la vie. He remains an associate researcher at the Institute for Research on Exoplanets (iREx) at the Université de Montréal and is proud to lead a dynamic team of researchers and artists dedicated to public education.
