Research Interests

My research focuses on understanding the structure, dynamics and functioning of ecological communities. I am exploring patterns in ecological networks across both natural and human-modified environmental gradients, and quantifying changes in network structure and ecosystem functioning.  Crucially, I investigate the dynamic processes behind these patterns using manipulative, often large-scale, experiments. I have a particular interest in the roles of both indirect interactions and weak interactions. I work on insects, primarily herbivorous insects and their parasitoids and host plants, and much of my research is conducted in tropical forests. I am part of the NERC funded human-modified tropical forests research programme working at the Stability of Altered Forest Ecosystems (SAFE) Project Site in Borneo.

Additional Information

I am a member of the editorial board for the journal Biotropica.
