Wilkinson is a conservation biologist specializing in studying and monitoring amphibians and reptiles. He started working with herpetofauna whilst an undergraduate and now nobody will give him a proper job. For eight years he was International Coordinator of the Declining Amphibian Populations Task Force and is currently Science Program Manager for the charity Amphibian and Reptile Conservation. John's PhD thesis was on toad conservation - it just made him realize how much more there is to find out.
