Research Interests

My research is focused on how to reconcile human demands, especially those for food and other agricultural products, with the conservation of birds and other biodiversity. I am interested in understanding the consequences of different food production trajectories for biodiversity, and in evaluating potential conservation strategies. I address these questions through fieldwork, data syntheses and spatial analysis. Collaborations include work with BirdLife International, the Royal Society for the Protection of Birds, Rainforest Alliance, the International Institute for Sustainability and the UNEP World Conservation Monitoring Centre. I am also interested more widely in ways of identifying and resolving trade-offs between conservation and development; in the ecology, conservation and restoration of tropical forests, especially in Brazil and West Africa; in the environmental and social consequences of biofuel development; in the role of sustainability standards in agriculture; and in defining conservation baselines and objectives.

I am also a Research Associate at Oregon State University in the USA, and an affiliated researcher at the International Institute for Sustainability in Rio de Janeiro.
