Research interests

I am a community ecologist interested in the factors that maintain biodiversity and ecosystem functioning. Particularly, my work focusses on how biotic interactions, such as between plants and their enemies or mutualists, contribute to biodiversity maintenance, the distribution of plant species and the functioning of ecosystems, and how such interactions vary along abiotic or biotic gradients. My research combines experimental field and laboratory studies to investigate these questions at both large and small spatial scales.

Keywords: plant population and community ecology, global change ecology, biodiversity research, plant herbivore interactions, plant pathogen interactions, biotic interactions, plant abundance, invasive species, conservation
