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.
