Cellular and Organismic Networks (About Me
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 Research
My current research is about microbiome assembly of butterflies 🦠🦋 (Research ). More broadly, I am interested in how microbial dispersal within plant-pollinator networks affects wild pollinator health and immunity — a question with direct relevance to understanding insect decline. My past work had the focus on microbiome function in plants (Past Projects ).
My Goals
I investigate Host-Microbe Interactions from a microbial perspective. My goal is an integrative understanding of host-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.

Frontiers in Microbiology 2025
Understanding how host-microbiome interactions respond to abiotic and biotic factors is key to elucidating the mechanisms influencing ecological communities under current climate change scenarios.
