I am interested in interspecific interactions and their effects on population and community dynamics, individual behaviour, and evolution. My research is mainly focused on plant-insect interactions, but I have also worked on systems involving host-parasitoid and plant-pathogen interactions. My current main project addresses the role of internally feeding insect seed predators (‘seed parasitoids’) in maintaining tropical forest diversity and structuring tropical plant communities.
