LIGM (Laboratoire d’Informatique Gaspard-Monge, UMR 8049) is a computer science laboratory located on the Champs-sur-Marne campus. It depends mainly on the CNRS and Université Gustave Eiffel, but also on École des Ponts ParisTech. It participates in the MSTIC doctoral school of Paris-Est Sup.

The lab gathers about 80 permanent researchers, and about fifty non-permanent researchers, in fundamental and applied computer science, divided into six teams: A3SI, ADA, BAAM, COMBI, LRT and MMSID

The LIGM is included in a LabEx (laboratory of excellence) at the interface between computer science and mathematics: “Bézout – Models and algorithms: from the discrete to the continuous“.
