Marie-Lou Gendron-Marsolais is an astrophysicist and Assistant Professor since 2024 in the Department of Physics, Engineering Physics and Optics at Université Laval. She holds the Canada Research Chair in Galaxy Cluster Environments, which aims to describe the internal (via the central supermassive black hole) and external (via the environment) influences on galaxy properties to improve our understanding of these gravitationally bound structures. She received her PhD in astrophysics in 2018 from the Université de Montréal. She was then awarded the prestigious European Southern Observatory (ESO) postdoctoral fellowship, which enabled her to independently pursue her own work on the study of galaxy clusters in Santiago, Chile, while working for the Atacama Large Millimeter/submillimeter Array (ALMA) telescope. In 2021, she joined the Instituto de Astrofísica de Andalucía, Granada, Spain, as a postdoctoral researcher to coordinate the efforts of Spanish astronomers in their participation in the Square Kilometer Array Observatory (SKAO) project, which will be the most sensitive radio telescope ever built. She is also passionate about scientific communication and the challenges of diversity in science.
