GDR-InF Annual Workshop 2025

Nov 12, 2025, 2:00 PM → Nov 14, 2025, 1:30 PM Europe/Paris

Carry-le-Rouet

The GDR-InF Workshop will be hosted at Carry-le-Rouet near Marseille in the venue Miléade Hôtel. 

The session of the 12th of November afternoon will be hosted at CPPM and we will go by bus at Carry-le-Rouet at 17h30. 

A return bus will leave Carry-le-Rouet Friday at 12:30, and take about one hour to reach Marseille.

The cost of the accommodation, meals and bus from Marseille to Carry-le-Rouet are covered by the GDR-InF while the travel to Marseille is not.
