Systematics and biogeography of Scaphander (Cephalaspidea)


Little is known about marine biodiversity and speciation in the deep sea.

In my PhD project, we use Scaphander (Gastropoda, Cephalaspidea), a globally distributed and predominantely deep-sea genus, as a model group. We aim to revise the systematics of Scaphander and to establish a dated, global phylogeny for this genus, so as to understand its historical biogeographic patterns and drivers of speciation.
