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