Student Poster Competition

The EFTF Scientific Committee has selected 28 finalists for the Student Poster Competition, distributed across 6 groups. A panel of judges will select a winner for each group during the poster session at the conference on Tuesday 21^st April, 2026.

Each finalist will have to present their poster to the judges in the dedicated area for the student competition, in rooms Boston 12–14 (B12–B14) at NH Leeuwenhorst (the conference venue). Note that this location is separate from the main poster area, the Atrium.

Some of the finalists will also be presenting their results in Lecture sessions, but they must additionally prepare and present a poster to the judges on Tuesday 21st April.

The winners of the competition will be announced during the Gala Dinner on Wednesday 22nd April.
