Research focus

In my PhD thesis supervised by Dr. Jörn von Döhren, I focused on taxonomy and systematics of Nemertea (ribbon worms) in Europe based on genetic data. Nemertea are unsegmented, mostly marine, vermiform animals of which approximately 1,300 species have been described so far. Morphologically differentiating between species is difficult in this group because only few external morphological characters are present. Because of this, I focused on molecular species delimitation methods (phylogenetic analyses, non-tree based, and tree-based delimitation methods) in order to discover cryptic species and help unravel nemertean phylogeny. Moreover, I analyzed the population structure and its dynamics in European nemerteans to understand variation within and between populations.
