Science interest

Marking a bumblebee in the field

Marking a bumblebee in the field

I am interested in wild bee ecology, nature conservation and public science communication. It is important to me that my scientific results provide a basis for nature conservation managements, so that we can counteract species extinction and contribute to the preservation of our environment. In addition to my work as a scientist, I am also involved in public science communication through various media, such as volunteer workshops about wild bee diversity and their conservation, through articles for magazines or creating critical segments for the environment program “Grün hinterm Ohr” of the free radio “Radio Corax”.

Research project

For my research project, I work closely with the Institute of Bee Conservation    of the Julius-Kühn-Institute Braunschweig. My aim is to investigate the impact of urbanization on wild bees. Using the methods of population genetics and molecular ecology, I investigate the influence of, e.g., road density, the proportion of impervious surface and the amount of green space within cities. But also parasitism and plasticity, e.g. body size, can provide important insights. With my research results, it will be possible to make conclusions about the current state of the genetic diversity and health of different wild bees in cities. Furthermore, the findings will help to be able to plan sensible and possibly necessary conversation management.
