Due to the ongoing CoVid19 pandemic, planning an international conference is hard at the moment. As we cannot foresee what the situation will be in mid 2022, we are planning for a hybrid format such that participants may join through virtually in case it is not possible or safe to travel to Hamburg. However, we do hope and also plan for a conference on site in order to not only get the most out of the scientific program but also meet and connect with colleagues and see the beautiful city of Hamburg.
