Oral presentations

• Oral presentations will follow the standard format (12 min + 3 min Q&A), while strictly selected solicited talks (one per session) are longer (25 min + 5 min).
• For all oral presentations (onsite and online) the presentation file needs to be uploaded to the conference platform at least 24 hours in advance of the start of the session. Upload opens on 15 July 2025. It is NOT possible to use your own notebook onsite.
• Online presenters are welcome to share their slides from their local device; the upload is requested as a back-up should the connection be weak.

Presentation preparation

Photo, screen capture or video taking of scientific material shown in any oral or poster presentation is not allowed unless the presenter authorizes this. Please inform the audience if you welcome photos or screen capture and their sharing on social media by including an official graphic "screen capture welcome" (download PNG, JPG, PDF)| "screen capture NOT allowed" (download PNG, JPG, PDF) on all slides.

• Recommendations by the Programme and Science Committee (PSC) for oral presentations

Upload of oral presentation and supporting material

• Presentation files for oral presentations are not shared outside your live session.
• All presenters (regardless of whether presenting onsite or virtually) must upload their presentation file at least 24 hours prior to the session's start time.
• The presentation file can either be uploaded by the contact author (who submitted the abstract) or the nominated presenting author of the abstract.
• The uploading author will be asked for agreement to the publication of their talk after the conference. For presenters who agree to the publication of their talk, recordings will be made available online after the meeting.
• All authors are encouraged to upload supporting materials to accompany their abstracts. These can be uploaded from 15 July 2025 and will be made available to registered conference attendees until 12 October. Modifications are possible throughout this period.
• A paid conference registration (either for on-site participation or virtual participation) is mandatory for the person uploading the presentation file in order to access the upload tool.
• A presentation file (i.e. slides for a talk) can be in *.pdf, *.ppt/pptx, *.pps/ppsx, *.png, *.jpg, or *.mp4 format. The size of presentation files is limited to 50 MB per abstract for *.pdf, *.ppt/pptx, *.pps/ppsx, *.png, and *.jpg files, and to 200 MB for *.mp4 video files.

Oral sessions

• Oral presentations are organised in oral sessions scheduled in specific lecture rooms at specific times. Oral sessions are scheduled in up to four time blocks of different lengths (75min | 90 min | 120 min) per day; larger sessions cover multiple time blocks, and may run over more than one day: session schedule overview.
• The time and length assigned for each contribution is given in the programme; this time includes discussion and change over.
• All oral sessions are run in a fully hybrid mode, using the lecture room settings for onsite attendees combined with Zoom for online participants. This setup will allow both onsite and online attendees to follow and present in the session equally.
• For online participation as audience, two options are available:
  • joining by Zoom, interactive participation;
  • watching the stream, without any chat, unmuting or camera activation, or screen sharing. Note that to give an online presentation it is necessary to join the session using Zoom.
• Onsite presenters must give a live presentation; online presenters are also requested to present live, but have the option to submit a pre-recorded talk should they be unable to be present due to time-zone differences, unstable internet connection, or other barriers.
• Onsite presenters: All onsite presentations are launched on the laptop in the lecture room, shared by the conference assistant in the Zoom session visible by onsite and online attendees equally. Onsite presenters control their slides themselves using the wireless presenter device at the lectern. This device is also equipped with a virtual pointer. Speakers have to remain standing at the lectern to ensure that the lectern camera catches their face and always speak into the lectern microphone: this is important as online attendees in Zoom would otherwise not hear what is said and would not be able to follow the presentation. Also, for attendees in the room, the microphone helps those who are hard of hearing.
• Online presenters will join the session through the Zoom meeting; they have two options how their presentation is shared:
  1. Their previously uploaded presentation file will be shared by the conference assistant on the lecture room laptop, and the assistant will also forward the slides when indicated by the presenter.
  2. Online presenters share their presentation from their local device, and can thus move slides forward directly.
  Once the presentation starts, the online presenter unmutes to speak to the onsite and online attendees, and may also activate the camera. The online speaker's camera feed is shown to the on-site attendees on the projector.
• Timer: A digital timer device will be operated by the conference assistant. The count-down of the time still available for the presentation – colour coded – will be visible in the top right-hand corner of the screen to both onsite and online speakers and the audience: green light for 9 minutes, then orange light for 3 minutes to conclude presentation; after 12 minutes the time appears red during the 3-min discussion time.
• In case the name of the presenting author has changed since the programme was published, please inform the session chair and the conference assistant in the room before the start of the session.
• Two separate types of material should be uploaded to the programme page: in addition to the (mandatory) presentation file, the platform provides the opportunity to show additional supporting material. Please note: The presentation file as well as supporting material can only be uploaded by contact or presenting authors after they completed and paid their registration for the conference. For more information on presentation files and supporting material see here.
• Any participation in a session, whether online or onsite, as presenter or attendee, in Zoom or through the stream, requires a registration for the conference.
• For online presenters, we strongly recommend downloading and using the Zoom client rather than accessing Zoom through the browser. To ensure sufficient quality, your bandwidth must have a capacity of at least 1 MBit/s upstream and 2 MBit/s downstream.

For more information on the conference format please see: https://www.ems2025.eu/programme/meeting_format.html

Lecture room equipment onsite

• Lectern with a lectern monitor, on which the presenter slides are visible.
  The lectern monitor is equipped with a webcam; as onsite presenter, adjust the angle if necessary, so your face will be properly visible on the screen (the conference assistant will assist you);
• Presenter device: All lecture rooms have a wireless presenter device at the lectern (virtual mouse) which also serves as a virtual pointer. The presenter device also serves to move the slides forward for onsite presenters.
• Microphone fixed at the lectern, hand-held microphone.
• The onsite speaker will see a timer/countdown on the lectern monitor, the audience and online participants will see the timer/countdown on the screen.
