Symposia

The IHC2022 scientific program is structured in 25 symposia covering each a thematic open to original results, innovative methods and multi-disciplinary cross-cutting views. Each symposium is organized in sessions with a keynote, oral and e-poster presentations, and welcomes academic and applied communications. This program has been elaborated and will be refined through constructive exchanges between the IHC2022 scientific committee, ISHS division chairs and the symposium conveners.
