Being asked to chair a conference session is a mark of recognition within your academic community. It is also a visible, public role that shapes the experience of speakers and audience alike. Doing it well is not difficult — but it does require preparation and a clear understanding of your responsibilities.
What Does a Session Chair Do?
The session chair is responsible for:
- Introducing each speaker and their paper
- Keeping presentations on schedule
- Facilitating the Q&A after each talk
- Managing difficult questions or disruptive behaviour
- Keeping the session running smoothly if technical problems arise
You are the host and the timekeeper. The audience and speakers rely on you to create an environment where research can be communicated and discussed effectively.
Before the Conference: Preparation
Good chairing begins before you arrive at the venue:
- Read the papers: Download and at least skim the full papers or extended abstracts in your session. You do not need to be an expert in every sub-topic, but you should understand the core contribution of each talk.
- Prepare speaker introductions: Write 2–3 sentence introductions for each speaker. Include their name, affiliation, and the paper title. Do not read a long biography — the audience wants to hear the research, not the CV.
- Know the timing: Confirm how many minutes each speaker has for presentation and Q&A. Write this on a card and keep it visible during the session.
- Contact speakers in advance: A brief email to confirm they have received their slot time, know where the room is, and understand any AV setup expectations is professional and helpful.
At the Venue: Before the Session Starts
Arrive at your room at least 15 minutes before the session begins. Introduce yourself to each speaker and confirm:
- How they pronounce their name (critical — mispronouncing a name in front of the room is embarrassing for everyone)
- Whether they prefer questions during or after the talk
- That their slides are loaded and working
Check that you know how to use the timing cards or lights, and that you have a clear sightline to the presenter from where you will sit.
Opening the Session
Start on time, even if the room is still filling. Sessions that start late tend to run late, compressing Q&A and frustrating speakers who go last.
A good opening takes under 60 seconds: welcome the audience, introduce yourself briefly, state the session topic, and outline the format ("we have four presentations today, each 15 minutes with 5 minutes for questions"). Then introduce the first speaker.
Time Management: The Core Skill
The single most important thing a session chair does is keep time. Speakers who run over time are a common problem. Your approach:
- Show a visible timing signal at 5 minutes remaining, 1 minute remaining, and time's up. Use cards, hand signals, or the room's timing lights if available.
- If a speaker ignores the signal, stand up — this is a universally understood cue that their time is ending.
- If they still continue, it is appropriate and professional to say clearly: "I'm afraid we need to move to questions now — could you give us your final conclusion?"
- Never let a speaker run more than two minutes over. The last speaker in the session should receive the same quality of Q&A as the first.
Facilitating Q&A
The Q&A is where the real intellectual exchange happens. Your role:
- Invite questions: "We have five minutes for questions — please keep questions concise so we can hear from several people." Then scan the room and point to raised hands.
- Have a backup question ready: Silence is awkward. Prepare one genuine question per paper in case the audience is slow to respond.
- Restate the question: If the room is large or the questioner is quiet, briefly repeat or paraphrase the question so everyone can follow the answer.
- Cut off monologues: Some questions are really extended comments. After 30 seconds without a question mark, it is appropriate to say: "Could you put that as a question for the speaker?"
- Cut off hostile exchanges: If a question becomes a debate or turns aggressive, step in: "That's a rich discussion — let's continue it in the break. Next question."
Handling Technical Problems
Projectors fail, slides corrupt, remote clickers stop working. Stay calm — the audience takes its cue from you. Keep the session moving: ask the speaker to describe their first slide while the technical issue is resolved, invite the next speaker to set up, or briefly open the floor for discussion on the previous paper while the problem is fixed.
After the Session
Thank each speaker after their talk and once more at the end of the session. A brief "Thank you to all our speakers for excellent presentations, and to our audience for their engaged questions" is a clean close. You are done — and you have done your field a genuine service.
