- The project will offer in-depth training in neurobiology of marine zooplankton, neuro-evo-devo and volume electron microscopy (vEM). One goal will be to obtain a high-quality full-body EM volume of a juvenile-stage Platynereis dumerilii and to analyse the volume in collaboration with other members of the group and other students of the ZooCell network - EM sample preparation, ultramicrotomy, serial EM imaging, image analysis - Extensive data analysis, including skeletonisation, working with AI-based segmentations, cell-type and connectome annotation, network analysis - Coordinating with other vEM and image-analysis projects in the network - Research visits to other laboratories of the ZooCell Network - Participating in regular ZooCell training events including courses and graduate schools. - The project will inform the evolution of larval form and sensory cell types Remuneration according to EU contract.
