Poster Presentation Guidelines

Posted in Participation Guidelines.

Thank you for contributing a poster presentation to the 5th Open Science Fair (OSFair 2025), taking place from 15–17 September 2025 at the CERN Science Gateway in Geneva. Below you will find all the necessary information and practical details for your poster session.

Poster Exhibition

A poster exhibition will be organised throughout the entire duration of the conference, with posters displayed prominently to maximise visibility and foot traffic. The posters will be mounted in the 1st Floor of the Globe of Science and Innovation, and will be accessible to all delegates during the conference hours. You can see the floor plan here. 

The main opportunity to present your poster will be during the Poster Session on:

📅 Monday, 15 September 2025
🕡 18:30–20:00
📍 Globe of Science and Innovation, 1st Floor

The poster session will take place during the conference welcome reception, which will be held across both the ground and first floors of the Globe of Science and Innovation. During this time, the demo session will take place on the ground floor, while the poster session will be held on the first floor.

All poster presenters are expected to stand by their posters and actively engage with attendees throughout the session, sharing insights, answering questions, and fostering conversation around their work.

One-Minute Madness: Poster & Demo Pitches

Before the Poster and Demo Sessions, we will host a One-Minute Madness session where both poster and demo presenters will briefly pitch their work to the audience. This fast-paced session is designed to give visibility to your contribution and encourage attendees to engage with you during the reception that follows.

The One-Minute Madness will take place on Monday, 15 September 2025, from 17:45 to 18:30, in the Science Gateway Auditorium A (Room 81/R-003A) at CERN.

All poster presenters are expected to give a one-minute oral pitch, alongside demo presenters. Each presenter will have exactly one minute to introduce their work in a clear and engaging way.

Immediately after the pitch session, the Poster Session will begin at 18:30 in the Globe of Science and Innovation, 1st Floor, where delegates will be invited to explore the poster exhibition and demo stations and interact with presenters in an informal setting.

Please prepare your pitch in advance to make the most of this opportunity!

Digital Materials & One-Minute Madness Presentations

To ensure wider visibility and long-term accessibility of your work, we kindly ask all poster presenters to submit a digital version of their final printed poster (in PDF format). These files will be uploaded to the OSFair website after the event and will serve as part of the online record of the conference.

In addition, if you wish to include a visual aid (e.g. one PowerPoint slide) during your One-Minute Madness pitch, please send it in advance to the organising team.
