Paul started his research career at the British Trust for Ornithology, working on a wide range of issues relating mostly to the relationship between farmland and woodland birds and their changing environments. He left the BTO for the RSPB in 1995 and ran a 4-year research project on Skylarks, gaining a DPhil from the Edward Grey Institute, University of Oxford, in the process. More recently, Paul has been involved in a wide range of research projects in the RSPB's International Research Team. This includes detailed ecological research on some of the world's rarest and most endangered species and work on wider issues such as climate change, international agricultural issues, remote sensing and monitoring and biogeography. Particular research interests are the implications of variable adult sex ratios for bird conservation, the ecology and conservation of threatened larks (Alaudidae) and the effects of international policies on bird populations. Paul has written nearly fifty scientific papers, as well as numerous book chapters, conference proceedings, books and scientific reports. Paul was appoined as an Editor of Ibis in 2006 and took over as Editor-in-Chief in 2009. Paul is also an elected member of BOU Council and Chairman of the BOU's Grants Committee.Email Paul.
