Simon Stuart "holds a doctorate from the University of Cambridge, and carried out field research on forest avifaunas in Tanzania and Cameroon. For 15 years he has worked for IUCN - The World Conservation Union, where he has served as Head of the Programme of the IUCN Species Survival Commission (SSC), and as Acting Director General. He has played a major role in applying science to conservation policy, for example in the Convention on International Trade in Endangered Species and the Convention on Biological Diversity (CITES). He is one of the people responsible for developing the new criteria for including taxa on the offical IUCN Red List of Threatened Species.
"Since 2001, he has been seconded to the Center for Applied Biodiversity Science (CABS) at Conservation International, where he is heading up a new unit on biodiversity assessment shared jointly between CABS and SSC. The first project of this new unit is the Global Amphibian Assessment, which is documenting the conservation status, habitat requirements, geographic distributions, threats and conservation measures for all 5,000+ of the world's amphibian species."
