Within the current sixth mass extinction, an evidence-based discussion of insect decline is of a major importance for combating biodiversity´s decline and providing consistent insect conservation guidelines. Therefore, my PhD research focuses on monitoring insects using genomics at two diversity levels. My first aim is to track the decline of insect populations since the beginning of the 20th century in Switzerland using museum specimens in order to unravel their evolution and genetic erosion. My second goal is to design and implement a new multi-locus genetic marker for Swiss Orthoptera to enhance the accuracy of species monitoring. Other fields of interest that I learned during my Bachelor and Master’s degrees, are phylogenomics and alpine ecology.
