Each meeting will consist of a Keynote lecture, a break where videos of our sponsors are being played, and two to four free paper presentations. The Keynote will speak for 20 minutes, with 10 minutes for questions. Each free paper will last for 7 minutes with 3 minutes discussion. In addition, a recording of each session will be uploaded to a dedicated YouTube channel.
Please register for each Session separately to get access! There is no registration fee.
Best Paper Award
After each session a team of experts will select the best paper of that session and the winner of the Best Paper Award.will be announced immediately after each session. This Award carries a prize money of 100 €. It is funded by donations from patients (originally targeted to support travel expenses of young researchers).
