Public voting! – We invite all conference participants to contribute to the selection of the winning poster.

With this award we aim to highlight posters which stand out for their clear communication. We will award outstanding examples that communicate scientific content, including to non-specialists, of the presented topic in a way that inspires and explains the subject and results well.


  • A selection committee will judge all posters that have entered into the competition, selecting a favourite based on communication and scientific criteria (see below).
  • In parallel, all conference participants can cast votes for all competition posters, assigning points between 0 and 10 for each of two criteria: communication aspects and scientific aspects.
  • The results from the committee selection and the summary of the public votes will then be combined, with weighting the committee results with 2/3 and the public vote with 1/3.

The Award

The author(s) of the selected poster presentation will receive one registration fee waiver for the EMS Annual Meeting 2025 and the poster will be highlighted on the EMS website. The award certificate will be handed over at the Awards Session 2025.

The awardee is also invited to become a member of the OPA selection committee for the EMS2025.
