Profile

Research interests

I am interested in the phylogeny of the basal, primary wingless hexapods (Collembola, Protura, Diplura, Archaeognatha, Zygentoma). Springtails (Collembola), as well as coneheads (Protura) and Diplura, are characterized by internal mouthparts. The evolution of this entognathous mouth part morphology has been under long discussion, but a satisfactory explanation is still missing. In addition, there are numerous unsolved questions about the endoskeleton and the evolution of the musculature. Thus, my special interest lies in the inner cephalic morphology of springtails, which I am studying mainly with the aid of high resolution synchrotron-µCT data and their three-dimensional segmentation.

Non-destructive morphological studies of old museum samples using modern techniques

The aim of this project is to use modern non-destructive techniques in order to asses important museum material. Traditionally, the preparation of the genitalia or other parts of the inner anatomy would require the preparation and thus the partial destruction of the sample which is often not possible with important type material. We avoid this by using approaches like µ-computed tomography to visualize the inner parts of these specimens in a non-invasive way.
