Research Description: We study a broad range of animal taxa using morphological and molecular tools to unravel the evolution and development of animal organ systems. Our team applies modern descriptive and molecular techniques to gain this information from a broad range of animal taxa using animals that can be kept in the laboratory but also collected from the local marine biota.Beside established morphological methods like confocal microscopy we are using 3D timelapse microscopy (4D-microscopy) and single blastomere injections of cell tracers to study the cell lineage of embryos of mainly marine invertebrates. Molecular approaches include the study of gene expression patterns and experimental methods to unravel the genetic framework underlying the formation of different organ systems, such as the CNS, the alimentary canal and other organs. Large scale sequencing approaches are used for gene discovery and are also used for the phylogenetic placement of the specific species. The research focus on the description of the development regarding cell lineage and gene expression includes understudied taxa such as local bryozoans, brachiopods, nematomorphs, aplacophoran molluscs, platyhelminthes, priapulids, polyclad flatworms etc. Molecular functional approaches are used to study the development of acoels, rotifers and gastrotrichs. Further collaborative approaches address the use phylogenomics to resolve metazoan phylogeny.
