The programme consists of Invited Talks and contributed Short Talks or Posters. We invite submissions for short, contributed presentations or posters.
If you would like to present your work, please submit a title and abstract (max 300 words). Based on the number and quality of submissions, we will determine the final format (short talks, posters, or a combination of both). This is an excellent opportunity for students and early-career researchers to present their work and exchange ideas with experts in the field.
