Nicolas Straube


Professor, Curator of ichthyology



My research foci lie on deciphering the phylogeny and systematics of deep-sea sharks, where I am making use of morphological and phylogenomic methods (including sequencing of preserved museum material) to explore adaptation, diversity, phylogeography and population structures in present and past.
