Access

If you arrive in Lille Europe station, first go to Lille Flandres station, either by subway, or by foot (it is just nearby). From Lille Flandres station, you need about twenty minutes to reach our department. Take the direct subway, direction "4 cantons", and get off at "cité scientifique". Once there you can follow in the same direction as the (aboveground) subway. You will soon see a building with a huge radio antenna on your right : it is the M1 building. Our department is just behind, in the M2 building. The workshop will take place in the M2 building, first floor, salle de réunions. Some maps.
