Research Expertise

Description

My research focuses on several topical themes in fundamental and applied ecology, including the determinants of biodiversity structure and function from genes to ecosystems, the combined influence of multiple anthropogenic stressors on communities and ecosystems, and the management and conservation of biodiversity and ecosystem services in the face of global change. I perform my research predominantly in streams and rivers, combining 'natural' field experiments with manipulative experiments performed at a range of scales, from whole streams, through stream-side channels to small mesocosms. By advancing knowledge and connecting science to policy, my research seeks to improve the management, conservation and restoration of aquatic ecosystems in the face of global change.
