After completing a PhD at Cambridge (1996), I worked with BirdLife International and IUCN, co-authoring a series of conservation action plans and books. I joined the EGI in January 2006, took up a Departmental Lectureship in January 2009, and became a Research Fellow of Somerville College in October 2009.
I work at the interface of evolutionary biology, behaviour, ecology and conservation. I use a range of methods, including field experiments and phylogenetic analyses, to understand the forces generating biodiversity, shaping phenotypes and structuring the natural world. The main themes of my research are as follows:
Further details about study systems and specific projects can be found in my group pages: Tropical Ecology and Conservation Biology.
I am interested in communicating about science and conservation to the public. My work has been widely covered in newspapers, on radio and on the web (see below), and features in several education sites (e.g. Today's Science). I have written popular articles about tropical research and ornithology (e.g. 1, 2), and produced local and regional field guides and education materials for tropical countries (e.g. hummingbirds; antbirds; Bolivian birds).
I am a Research Associate of the Smithsonian Tropical Research Institute, a Senior Research Fellow of the Centre for Tropical Research (University of California, Los Angeles), and a member of the Conservation Biology Association, the Association for Tropical Biology and Conservation, the European Society of Evolutionary Biology, and the Oxford Centre for Tropical Forests. I currently convene undergraduate courses on Evolutionary Ecology and Quantitative Methods, and teach on Adaptations to the Environment, Sensory Ecology and Tropical Ecology. I also lecture on science and the media to graduate students, and run bird weeks for the annual undergraduate fieldcourses at Orielton, Pembrokeshire, and Danum Valley, Borneo.
