As a former member of the S&K team, Prof. Dr. Carina Lüke and her new Würzburg team continue to cooperate in research with the Dortmund S&K team. We share research interests in language development disorders and multilingualism. A first joint contribution will be given at the dbs symposium in March 2023 as a presentation by Dr. Isabel Neitzel, Jannika Böse, Jun.-Prof. Dr. Anna-Lena Scherger and Prof. Dr. Carina Lüke.
