Profile

Areas of responsibility

Since January 2019 I am responsible for various science reporting obligations, panel work and the coordination of the LIB PhD Program.

Between May 2014 and Dec 2018 I coordinated the German Barcode of Life project (GBOL) as successor of Dr. Stephanie Pietsch. Before that I worked as postdoctoral researcher in the Leibniz SAW FREDIE (FREshwater Diversity Identification for Europe) project with Fabian Herder. This project was aimed at setting up - and critically testing - a voucher-based DNA barcoding reference system for virtually all species of European freshwater fish, mollusks and mayflies, from Portugal to the Ural. My special focus is on freshwater fish evolution and diversity. Please visit the GBOL & FREDIE sites for details, partners, pictures and progress. Before I came to ZFMK/LIB Bonn, I worked on phylogenetic and evolutionary relationships of Nicaraguan Midas cichlids (Amphilophus spp.), on fish taxonomy, and have been involved in the DNA Bank Network and different DNA Barcoding projects.

Research interests
