Symposium structure

The scientific programme of Sardinia 2023 is structured in 8 parallel tracks and includes more than 450 presentations selected according to quality by the Programme Committee.

The presentations are organised in Oral sessions, Workshops, Active Labs and Poster sessions. Oral sessions last 90 min and include 5 or 6 presentations and a Discussion. Workshops are primarily addressed to experts and seeded by a number of introductory lectures delivered in order to open discussion among participants. Active labs are practical design laboratories during which participants will have the opportunity to apply theoretical notions learnt during the oral sessions to an actual case study or a practical activity with colleagues and experts as part of a working team.
In addition to these traditional sessions, the Symposium includes four plenary Focus Sessions, to be held in the afternoon, dedicated to specific themes of high public interest. A moderator, after a state of the art presentation and statement made by 2-3 experts in the field, will guide the discussion among the experts and the audience. The format and the session settings are similar to a "talk show".


Posters are continuously accessible in a dedicated hall and discussed in the presence of authors on Monday, Tuesday, Wednesday and Thursday afternoon from 16:30 to 17:00. The poster session will be available also digitally, allowing pre-recorded video presentations, download of the individual posters and online discussion with the Authors.
