Pollination processes are at the heart of well-functioning and resilient ecosystems, yet pollinators are currently facing multiple threats. My aim is to contribute to a deeper understanding and effective mitigation of disruptions within the intricate plant-pollinator networks in semi-natural grasslands. Within my PhD project, I am interested in discovering

(1) how pollinator declines influence plant community composition and plant trait expression in grassland plant communities
(2) how pollinator-mediated changes in the plant community affect pollinators again in return, and
(3) what these effects mean for ecosystem functioning and resilience to stressors like extreme weather events.  

I bring a background in global change ecology to this project, a specialization I chose for my master's degree at the University of Natural Resources and Life Sciences (BOKU) Vienna. In the past, I have also been involved in the Austrian Panel of Climate Change's report on health, demography and climate change, studied butterfly facing challenges due to habitat fragmentation at the Swedish University of Agricultural Sciences (SLU) and worked as a field assistant in a project on pollinator exposure to pesticides in red clover fields here at Lund University.
