Poster

All posters will be up all week and can be visited at all times.

The maximum space for poster presentations is A0 portrait format (width: 841 mm, height: 1189 mm). Poster spaces will be available for accepted abstracts only.

In addition, we offer a 1 min poster flash talk for each poster.
For this, please prepare 1 (at most 2) slide(s) as pptx or pdf and name it according to the page in the book of abstracts.

A detailed program and the book of abstract can be downloaded on the right!
