Chief Executive, British Trust for Ornithology and Honorary Professor of Biological Sciences, University of East Anglia

My work has focused on diagnosing causes of species decline and developing policy or practical solutions to stem or reverse those declines. I have a strong interest in the impact of land-use change on bird populations particularly birds in agricultural landscapes in Europe and Africa.

I also have long standing interests in the decline of Afro-Palearctic migrant birds and the links between livelihoods and conservation in and around tropical forests. I have supervised a large number of PhDs both in the UK (UEA, St Andrews and Oxford) and abroad (Uganda, Ghana, Liberia, Nigeria and Kenya) and am a passionate advocate for equality, diversity and inclusiveness in conservation science and ornithology.

I am currently CEO of the British Trust for Ornithology: a UK-based environmental NGO representing a unique partnership between citizen scientists and professional staff. It delivers long-term nationwide data on population trends of breeding and wintering birds, alongside research to help understand the drivers of those trends and seeking to engage and enthuse volunteer observers.
