A scientific day organised by the laboratory will be held on 11 July 2022 at the École des Mines de Paris in honour of François Ducastelle. The day will be a balance between scientific and memorial aspects combining past and present science, testimonies, and companionship throughout his long research career.
The meeting will be held in Dourdan (Paris area, France) on May 9-13 2022. Invited talks, tutorials, contributing talks, poster sessions, and social events are scheduled. Instructions for submitting an abstract or more information about the meeting can be found at https://howdi2022.sciencesconf.org/.
