Autobiography

After completing a PhD at Cambridge University, 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 became a Senior Lecturer at Imperial College in April 2015.

Research Activities

My research investigates the processes generating, sustaining and structuring biodiversity. I use a combination of experimental, phylogenetic and spatial mapping approaches to test theory, and to explain microevolutionary and macroevolutionary patterns over a range of spatial and temporal scales. Most of this work uses the world’s birds as a study system, but increasingly focuses on other components of biodiversity, from primates and reef fish to insects and plants. I am interested in using these insights to help us predict and manage the response of ecosystems to global change, with applications from biodiversity conservation to environmental policy. Although recent work is global in scope, my main interest lies in tropical systems, especially tropical rainforests. Current areas of interest are:

  • Sensory ecology, signal evolution, and cultural evolution
  • Speciation and diversification
  • Species interactions
  • Ecological impacts of climate and land-use change
  • Sustainable management of ecosystem function and services

Media and Outreach

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. 12), and produced local and regional field guides and education materials for tropical countries (e.g. hummingbirds; antbirds).

Other Information

I serve on the Editorial Board of Evolution (2014–). I am also 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 Oxford Centre for Tropical Forests.
