We are very happy to be a part of the CRC Network CataLysis. The membership in this network offers us a lot of opportunities e. g. stimulating lectures and discussions. Above all, we are looking forward to the international network conference in Kassel/Germany in early May. There we will present our CRC to the other CataLysis members and get an overview of the topics of the participating CRC's. Thank you very much for this opportunity, it is an honor for us.
