Talk Title: Neofunctionalization of Toll signaling: the evolution of dorsoventral axis formation in insects

Siegfried Roth studied biochemistry and philosophy at the university of Tübingen. He obtained his PhD at the Max-Planck-Institute of Developmental Biology (Tübingen) in the group of Christiane Nüsslein-Volhard with a work on axis formation in Drosophila. As a postdoc he worked at Princeton University in the group of Gertrud Schüpbach on the origin of polarity during Drosophila oogenesis. In 1995 he was recruited as a group leader at the Max-Planck-Institute of Developmental Biology. Since 1998 he is Professor for developmental biology at the university of Cologne. His research area is the evolution of developmental mechanisms, in particular the evolution of dorsoventral axis formation in insects.
