The principal theme of the EMBO Workshop is the Molecular and Developmental Biology of Drosophila. Supported by EMBO over four decades, this will be the 22nd biennial “Crete meeting”. With the aim to promote exchange of ideas and foster interdisciplinary collaboration, this EMBO Workshop brings together established and junior group leaders using Drosophila to understand principles of development, cell biology, neurobiology, behavior, genetics, evolution and population genetics.
