In the center of our research is a frequently underestimated life stage: the larval stage. Several groups of Euarthropoda, in particular, are characterized by highly differentiated larval stages, especially many representatives of Decapoda and Insecta, but also some others. These larvae play a significant role in the ecosystem, not least because of the biomass they represent.
In addition to modern animals, we examine exceptionally well-preserved fossil larvae. This allows us to track changes in the morphology of these developmental stages over geological timescales.
In an ongoing project I am investigating the explosive diversification of ice fishes in antarctical seas, a rare phenomen for the process of adaptive radiation.
Methods and approaches

We investigate the diversity of morphology in these larval stages using modern imaging techniques (super-macrophotography, microscopy, µCT scanning) in combination with numerous contrast methods (cross-polarization, fluorescence, phase contrast, dark field) and software-based optimization (image fusion, panorama stitching, HDR, virtual surface reconstruction). Observed morphologies are discussed in an evolutionary phylogenetic context, and the range of variation is quantitatively assessed.
Ultimately, our approach allows us to quantitatively assess changes in the morphological diversity of ecologically important groups over time. This approach therefore provides important foundations for other, more ecologically oriented fields such as biodiversity research and conservation biology.
