Currently I am participating in the joint research project BEATLE with Dr. Anne-Christine Mupepele in partnership with Dr. Arndt Feuerbacher from the University of Hohenheim. Our project aims to generate knowledge on how policy and society can transform towards a biodiversity-friendly land-use and food system. Specifically, my Ph.D. focuses on the quantitative assessment of relationships between land-use changes, the resulting changes in habitat for species and species groups, and the provision of monetary and non-monetary ecosystem services.
