I am a Postdoctoral Researcher in the gorup of Prof. Joyce, working on an SNSF funded project on turtle evolution. I did an undergraduate (B.Sc.) and Master's (M.Sc.) degree in Geological Sciences at the University of Munich (LMU & TUM). I finished my D.Phil at the University of Oxford in late 2018, and subsequently started in Fribourg in February 2019.


My research is focussed on the morphological evolution of turtles, and I use digital 3D anatomy and shape data to investigate the phylogeny of turtles, as well as form-function relationships and the patterns and pace of morphological change across ecological transitions. My D. Phil research was primarily focussed on transitions to marine lifestyles in turtles, which happened independently a few times across turtle phylogeny. I use phylogenies for reconstructing character evolution, for computing rates of evolution, and for dating the origins of modern turtle diversity.
