Hello there! I consider myself as Microbial Molecular Ecologist (mi·cro·mole). I have been trained cross-disciplinary in Microbiology and Chemical Ecology at the interfaces of molecular and organismic disciplines and combine Ecological Field Work with DNA Metabarcoding. (CV )
My main research is about Microbiome Assembly of Butterflies 🦠🦋 (Research ). I am particular interested how solitary pollinators acquire their microbiota. My broader interests are microbial transmission among Plant-Pollinator Networks in the light of Pollinator Health and Immunity. My past work had the focus on Microbiome Function in plants (Past Projects ).
I investigate Host-Microbe Interactions from a Microbial Perspective. My goal is an integrative understanding of Microbiomes in the light of macroecological theories. I would like to ad Host Movement to current Metacommunity concepts, as it changes connectivity of Local Habitats and removes Microbial Dispersal Limitations.
...what I consider is the key aspect of the future of education in the life sciences, a curriculum based on the ecology and evolution of the biosphere that integrates microbiology and macrobiology into a unified systems biology.

LepEU, the European Lepidopteran Population Genomics Consortium, was launched in 2023 to coordinate continental-scale collections and generate population-level genomic data for butterflies and moths across Europe.
