I am interested in the evolution of vertebrates in general, including marsupials, birds, almost every placental mammalian order, lizards, snakes, crocodiles and fishes. Besides reconstructing and dating their evolutionary tree, placing the events into larger contexts of e.g. biogeography, plate tectonics and climate is exciting. The increasing amount of genomic data show that evolution may not be a bifurcating process, but seeing it as a network will enhance our understanding of evolution. Currently – as of January 2017 – I am interested and working on the following topics for which PhD, master or project students are welcome:
Mammalian phylogenomics (see D2.3)
Arctic adaptation (see D2.4)
Genomics and speciation (see D2.3)
Genomics and climate (environmental) change (see D2.4)
The basic divergences of crocodiles
The evolution of marsupials

I am interested in evolutionary biology in general, but mostly in biogeography, phylogeography and phylogenetics. I am also enthusiastic about learning new genome sequencing techniques and bioinformatics to understand evolution based on large-scale genomic data. Currently, I am working on evolutionary genomics and population genetics of giraffes. The aim is to investigate hybridization and gene flow between four putative giraffe species using next generation sequencing data in order to verify the current taxonomic proposal and to understand their speciation process. For my B.Sc. and M.Sc. studies, I have worked on the phylogeography and conservation genetics of xenarthran species, mainly anteaters and sloths.

I am interested in evolutionary biology and taxonomy of mammals. Since visiting Namibia for my Bachelor thesis I am fascinated of large African mammals. Currently, my research focuses on evolutionary genomics and population genetics of giraffe (Giraffa carmelopardalis). The aim is to identify structure and gene flow of wild giraffe populations based on mitochondrial and nuclear markers in order to examine the need for a taxonomic revision in giraffes.

I am interested in the evolution of genomes and genomic diversity in general, including phylogenetic as well as population genetic questions. In my current work, I try to uncover the impact of bottleneck events on the genetic diversity of baleen whales and I would like to understand how depleting population sizes affect these genomes. Therefore, I analyze gene flow and hybridization patterns between whales, but I also aim for new genome publications and phylogenetic insides. With this, I hope to support the conservation and management of whales. Additionally, I worked a lot with genomes of parasitic fungi that possess fast evolving and diverse contents of genes responsible for their pathogenetic behavior, called effectors. In so doing, I tried new machine learning tools that predict these effectors and evaluate their reliability. Eventually, this will speed up our process of finding and analyzing those genes.
