Thank you for chairing. A good chair is what turns a set of talks into a session.
Be in the room fifteen minutes before your session. Meet your speakers, check the pronunciation of their names, and confirm their affiliations.
Timing is the chair’s responsibility. Agree your signals with each speaker in advance. The standard is a card at two minutes and one at zero.
Have one question ready for each speaker so that discussion never stalls. Take questions from across the room, and ask questioners to state their name and affiliation.
Thank the speakers, summarise in a sentence or two, and hand over on time so the next session is not squeezed.

Chairs of oral abstract sessions are also asked to nominate one presentation for the best-abstract award. Nomination forms are provided at the chair briefing and must be returned to the scientific secretariat before the close of the second day.
Judge on the quality of the science and the clarity of its communication, not on seniority. The award exists in large part to give early-career researchers visibility.
