By RER A
Directions of RER (and Métro) lines are always named by the end destination, for RER to Noisy-Champs this is “Marne-la-vallée – Chessy” or “Torcy”. The RER line splits outside Paris at Val-de-Fontenay stop, furthermore the trains do not stop at all stations, hence you have to check the billboard installed on the platform for the “Noisy-Champs” stop.
Noisy-Champs is 30 minutes away from the center of Paris (“Châtelet Les Halles”), 60 minutes from “Antony” (interconnection with Orly airport) and 75 minutes from Charles De Gaulle Airport. Trains are scheduled more or less every 15 minutes.
Noisy-Champs station has two exits. You should go out by the one at the head of the train coming from Paris and then follow the Campus map to reach the Copernic building (the laboratory is at the 4th floor, accessible by elevators), the Coriolis building or the building of ESIEE Paris.
