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.
