Group Discussion Meetings (GDM)

After reviewing and examining the session papers, our Special Reporters compile questions that are not specifically aimed at the papers' authors, but are synthesized from common issues and trends identified across the papers. Session attendees are encouraged to share their views and experiences in response to these questions. This provides the opportunity for broader responses and participation in the Group Discussion Meetings.
Two or three slides for a 5-10 minute presentation are the usual format. The meeting convener asks each contributor to take the floor and present their contribution to the audience, with a speaking time schedule set up in advance.
Authors and intended contributors should prepare their slides in advance and make them available to the organizing committee for prior review and optimal organization of the meetings. Templates and instructions will be posted on this page a few months before the session.
Contributors will upload their prepared contributions directly through their personal account on the registration portal.

For details see Group Discussion Meetings (GDM) page.

Poster Sessions

Poster Sessions are a unique opportunity for authors to present their Papers in a convivial working atmosphere during fruitful exchanges with the Session Delegates. A large space is dedicated to this event. Each author will have their own panel with a printed poster displayed. The meeting duration is usually two hours but can be adjusted according to the number of presentations. Authors will upload their presentation for the Poster Session on a dedicated website. Authors or co-authors who cannot attend the Session may then ask someone to present the Paper - a colleague for instance - so that each Paper can be presented at the Poster Session meeting. Full instructions for the preparation of the posters, along with appropriate templates, will be available on this page.
