Your session

All session chairs are requested to consider the following points for their session:

Prepair your session

• Be in the room where you will lead the session at least 20 minutes before the session starts.
• Coordinate with the technical staff and speakers at the venue.
• Make sure you have a timer and, if necessary, signs to show the remaining time.

Start of the session

• Please start the session on time.
• Briefly introduce yourself and explain the session to the audience.

Keep to schedule

• Please stick to the times listed in the conference programme.
• Inform the presenters in good time before the end of their talk. Usually, presentations will have the following durations:
  Contributed talks: 15 minutes (12 min talk + 3 min discussion/speaker change)
  Invited talks: 30 minutes (25 min talk + 5 min discussion/speaker change)
  Plenary talks: 45 minutes (without discussion)
  The exact length of the individual lectures can be found in the conference programme.
• Please ask the speakers to finish their presentation when the allotted time has expired. Be polite but firm.
• Please finish the session on time.

Moderation of the question and answer session

• The audience has the opportunity to ask questions after each presentation. Actively invite the audience to do so.
• Please also make sure to keep to the given time frame.

Absent speakers

• If a speaker does not appear, allow the previous discussion to continue or suspend the session until it is time for the next scheduled presentation.
