My major research interest is the postembryonal development of arthropods. In my master thesis I am currently comparing developmental modes in different insect groups. In my bachelor thesis I laid my focus on polyneopterous insects (e.g., grashoppers, mantids, cockroaches, or earwigs) as the phylogenetic position of many of these groups is still debated. As detailed studies on the development of these insects are rare, I documented the separate nymphal stages of Hierodula membranacea, a praying mantis. Additionally, I investigated the morphological and functional biological changes of the wings during the development of Phasmatodea (stick and ghost insects) and Orthoptera (grasshoppers). In both cases, the insects were documented with macrophotography under polarised light directly in alcohol. Based on these data I looked for characters which could be helpful for understanding the relationships within polyneopterous insects.
