I am a university teacher with independent research interests, which are summarised below. For the past 20 years I have taught undergraduates at Cambridge University, covering whole organism biology courses (including those relevant to evolution, physiology, behaviour and ecology). Over the years I have developed a special focus on bringing students up to the highest standards of science writing. More details of these courses can be found here.
Taxonomy, ecology, evolution and conservation, especially on islands. Plants and animals, especially molluscs, reptiles and bats.
Recent work has concentrated on evaluating the status of the world's invertebrates through my role as Chair of the IUCN/SSC Terrestrial and Freshwater Invertebrate Red List Authority and climate change, recently founding the Climate Change Working Group of the IUCN SSC Amphibian Specialist Group. In 2013 I became active in Partula snail conservation after a gap of 20 years. These snails are emblematic of the biodiversity crisis, with 51 of the French Polynesian species being driven to extinction within two decades. 12 species may survive in the wild and a further 11 survive only in captivity. In 2017 I surveyed the surviving populations and am now investigating the impacts of introduced predators, especially the flatworm menace and the impacts of tree snail extinction on forest health.
