Coming to the COPERNIC Building at the University of Marne-la-Vallee by public transport (RER, line A)

(the laboratory of Mathematics is at the end of the west wing, 4th floor) station NOISY-CHAMPS (when coming from the center of Paris, that is many stations before the last one, called CHESSY-MARNE-la-VALLEE, which is the station for Disneyland and for the TGV connection and NOT for the University)

For more information, check the site of the Paris area Public Transport (RATP)
Leave the station by the extremity - at the head of the train when coming from Paris - at the tail of the train when coming from Marne-la-Vallée-Chessy. Cross the railway line inside the station building, turn left and go along the railway line (you go along a huge administrative building of "La Poste" and see the Hotel IBIS in front of you). At the first crossing, turn right and walk until a crossing with a monument called "the axis of the world" (high arrow which is parallel to the line joining the Earth's poles). At the monument, turn left : our building is the first one on the right, just after the crossing of Boulevard Descartes and Boulevard Copernic.

Coming to the COPERNIC Building at the University of Marne-la-Vallee by car via Highway A4

Coming from the WEST (Paris)

Paris or circular highway A86: leave the highway at exit "CHAMPS", turn left and cross the highway, turn right at first traffic light, then left at the first roundabout towards boulevard Copernic (see map).
Our building (Copernic) is the first one on the right ; so you arrive behind the building, where there is a huge parking place (turn right just before the building to enter this parking lot).

Coming from the EAST

Caution : the way out "CHAMPS" is just a half one : you have to go to the next one (NOISY-le-GRAND) and come back ; then do as when coming from the west.

Coming to the laboratory of MATHEMATICS inside the COPERNIC building

When you enter the hall by the main entrance (on the RER side), you see two escalators in front of you : do not use them but go to the lifts which are behind them. When stepping out of the lifts at the 4th floor, turn twice on your right : you are in a long corridor and our laboratory is at the end of it. If you enter the building by coming from the parking place, you arrive behind the lifts.
