Interests and expertise
I am a conservation ecologist who works particularly on threatened taxa. Much of my work concerns the effects of human actions such as land use change and direct exploitation on wildlife, including tropical birds, but also on mammals, amphibians, and UK species/systems biodiversity. I work mainly through PhD students and research assistants, both from within Europe, and from Asia, Africa and South America. Capacity building for conservation research within developing countries is a key aim of my work.
Impact
Our hope is that the research we do has a positive impact both on the threatened taxa we study, and for the often disempowered people who live along side them in the tropics. Our Impact case Study on tropical birds was one of four submitted to the REF UoA7 - these scored highly in terms of global impact ranking us 5th among UK universities in our field. You can read about it here Impact Case Study - protecting-tropical-birds
