Instructions for Speakers and Session Chairs
Research talks last up to 20 minutes. Session chairs moderate and make sure things stay on schedule.
Each talk concludes with two written down questions (one easy and one difficult) related to the take-home message of your talk. The questions shall be answered (and answerable!) by the audience.
After the two questions, there will be a few minutes for comments from the audience and replies from the presenter. The session chair moderates this part.
For panels: Each panelist prepares an input statement of 4 minutes sharing their view. Send any slides by January 31 to the moderator for integration.
