Research Interests
I am a broadly trained agroecologist, specializing in biodiversity conservation and ecosystem services in both tropical and temperate agroecosystem. The overarching aim of my research is to explore how habitat structure at local and landscape scales influences species diversity and ecosystem services provided by arthropods, such as biological pest control and pollination, in order to create solutions for more resilient and sustainable agricultural production.
Central research interests:
- Landscape ecology
- Ecosystem services
- Biological pest control
- Biological conservation in human-modified landscapes
