On March 10 & 11, the second retreat of the SFB1552 took place in Kirchheimbolanden. This time, the retreat was all about identifying and establishing collaborations. To this end, half posters were initially prepared, which were supplemented during the retreat with possible collaborationsand their specific subject matter. We would like to thank all participants for their active participation and the lively discussions. In addition to the requirements for the use of ELNs, other internal SFB1552 topics were discussed in depth in break-out sessions. Finally, new Early Career Researchers Representatives were also elected and we would like to congratulate Marvin Manz and Benjamin Strücker on their new positions.
