Workshop 2022

November 14 (2 PM) – November 16 (~12 noon)

The main objectives were to initiate:

– discussions with scientists whose expertise is likely to meet the scientific challenges addressed by the project-team,

– new actions and collaborations, in France and with colleagues from foreign institutions.
