Georg Brenneis

Dr. Georg Brenneis is a researcher in Integrative Zoology at the University of Vienna, Austria. His research focuses on arthropod development, morphology, and diversity within a phylogenetic and evolutionary framework. Affiliated with the University of Vienna, Naturhistorisches Museum Wien, and Universität Greifswald, he specializes in marine sea spiders (Pycnogonida) and their neural, developmental, and taxonomic studies.

Research Interests: Dr. Brenneis investigates the arthropod nervous system, with emphasis on neurogenesis, neural differentiation, and neuroanatomy in sea spiders. He also studies adult neurogenesis in non-insect arthropods like crayfish, aiming to compare this across major arthropod groups. Additional interests include external morphogenesis, muscle development, regeneration in sea spiders, life-history features, taxonomy, and phylogenetic relationships within Pycnogonida.

Recent Research Trends: His 2020 work on Pallenella in Tasmanian waters used integrative taxonomy combining morphology and genetic markers (COI and ITS) to identify 13 sympatric species. Earlier studies (2011-2019) explored embryonic/postembryonic development in Pseudopallene, Antarctic species, and ventral organ neurogenesis. Collaborative projects span phylogenomic analysis, biogeography, and regeneration mechanisms.
