Director of the Planétarium, Olivier Hernandez is an astrophysicist, expert in instrumentation and specializing in galaxies and exoplanets.

He earned an engineering degree from the École centrale de Marseille and a Master’s in Physics from the Université de Montréal. He also holds a Ph.D. in Astrophysics. His dissertation, completed jointly at the Université de Montréal and the Marseille Astrophysics Laboratory, focused on the dynamics of galaxies.

Co-founder and former iREX Coordinator, he was also the Director of Operations for the Mont-Mégantic Observatory (OMM - Observatoire du Mont-Mégantic), which includes a 1.6 m telescope and an experimental astrophysics research centre of national and international renown; he was also a Lecturer with the Université de Montréal’s Department of Physics.

His main fields of research are the kinematics and dynamics of barred spiral galaxies, mainly the study of the distribution of visible and non-visible matter. He also works on the development of high-tech specialized astronomical instrumentation for studying galaxies and detecting and characterizing exoplanets.

His responsibilities as Project Director at the OMM led him, among other things, to be the Coordinator in Montréal on the international SPIRou and NIRPS projects, two instruments that will make it possible to detect telluric planets, i.e. those comparable to Earth in size, by 2021. He was also the Montréal Project Coordinator for the development and construction of one of the four scientific instruments on the successor to the Hubble Space Telescope, the future James Webb Space Telescope (JWST). The JWST Canadian instrument, the design of which is led by UdeM professor René Doyon, is used to detect the atmosphere of exoplanets and determine their chemical composition, so as to detect water and potentially life, by means of other biomarker gases of biological activity, such as oxygen and methane.

Lastly, Olivier Hernandez coordinated a team of researchers, engineers and technicians who manage and develop all the astronomical instrumentation for the Mont-Mégantic Observatory, with funding from the Canada Foundation for Innovation (CFI) received in 2009.

Currently Director of the Planétarium, he is also responsible for research and ecological transition as well as the founder of the equity, diversity and inclusion committee at Espace pour la vie. He is still Research Associate at the Université de Montréal's Institute for Research on Exoplanets (iREx) and has the pleasure to lead a dynamic team of researchers and artists dedicated to the education of the great public.
