Research Interests

I am interested in a wide range of topics in ecology and conservation, with particular experience of climate change and the ecology of birds and urban areas. I am passionate about ensuring that conservation interventions are based on evidence, and that their outcomes are monitored. I currently work as part of Bill Sutherland's group; my roles include organising the annual horizon scan of global issues for conservation, and acting as managing editor of the journal Conservation Evidence.

Previously I worked as a research ecologist for the British Trust for Ornithology, and was involved in projects investigating the impacts of climate change on natural populations and factors affecting long-distance migrant birds. Before that I worked for the RSPB, running a project investigating the causes of the decline of the urban house sparrow population in London.
