The conference issues by a joint initiative within the Italian and French communities working in sub-Riemannian geometry and control. It includes speakers from several countries and welcomes international participation from all over the globe. The conference is aimed at exchanging on the latest results in the research areas of sub-Riemannian geometry and geometric control theory. This will be the opportunity to celebrate the accomplishments of Andrei Agrachev in these fields, in the occasion of his 70th birthday.

The conference will be held in the setting of Palazzone di Cortona (owned by the Scuola Normale di Pisa), from the 27th to the 31st of March, 2023.
