POSTER AWARDS
Awards for the best Visual Presentations 2025
The Poster Awards are an important part of the conference, where all visual presentations are evaluated and judged based on structure, presentation and scientific contribution to select those that excel in their topics.
We would like to emphasise that the posters are an equally important part of the conference programme, and we are even more pleased to have the presentations in physical form again this year.
The best posters have been selected and acknowledged in the closing session of the conference.
Congratulations to the winners 2025!
