I am a Professor of Freshwater Ecology in the Department of Zoology, and a Tutorial Fellow at Somerville.
My main research interest lies in understanding individual-to-ecosystem level responses to environmental change, including warming, invasion, pollution and habitat loss. I am particularly interested in interactions among these stressors, and how stressor effects cascade through food webs with implications for ecosystem processes and services. I use a combination of field studies across both natural and anthropogenic stressor gradients, manipulative experiments and meta-analyses to seek general predictive rules in multiple stressor effects. Most of my research is in freshwater ecosystems, spanning from the Arctic to the tropics.
