All events will take place in the Aula Magna building, more precisely in the Foyer du Lac.

Walking direction from Martin's hotel: follow the "Cour Michel Woitrin", a pedestrian street running alongside the right of the large Aula Magna glass building, then continue on the "Passerelle de l'Aula", a bridge going down and once you reach the level of the lake, walk back towards the Aula Magna through the parking lot ; entrance is located at this location.

The abstracts of all talks and posters are available in the book of abstracts (PDF file).
