In the early 1990s he built up a research group at the École normale supérieure de Lyon (ENS-Lyon) in collaboration with the nearby Lyon Observatory. In 1995, the Centre de recherche astronomique de Lyon was founded, known as the Centre de Recherche Astrophysics Lyon (CRAL) since 2007. Chabrier continues to lead one of the research groups at CRAL. He is also a research director at the Centre national de la recherche scientifique (CNRS).

Before the discovery of brown dwarfs in 1995, Chabrier helped develop the theory of their structure in collaboration with Isabelle Baraffe, France Allard and Didier Saumon
