ARIA 1st Workshop (8-10 March 2023)


The ARIA Workshop will be an open international conference on Reduced Order Models aimed to progress towards key advances in modeling multi-scale nonlinear physical phenomena. The workshop will follow a high standard in the selection of presentations and posters by a programme committee of international experts of the domain.

The workshop is sponsored by the European Commission, Inria Bordeaux, CNRS and Bordeaux University.

Date and Venue

ARIA Workshop will be organized on 08 (afternoon)-10 March (noon) 2023 at:

Centre Inria de l’université de Bordeaux,  200 Av. de la Vieille Tour, 33405 Talence

Meeting room: Ada Lovelace – 3rd Floor



The scientific coordinator of ARIA project is Angelo Iollo – Inria de l’université de Bordeaux.

Other workshop organizers are: Tommaso Taddei and Michel Bergmann – Inria de l’université de Bordeaux.

The admin contact of the workshop is Linh Nguyen – Inria Université Côte d’Azur ( ) and Anne- Laure – Inria de l’université de Bordeaux (  )


The registration has been closed as we have reached maximum number of participants. For other special request, please contact .
