Matthew Fisher, Imperial College London
Matthew Fisher is an exceptional researcher who led the first case study showing unambiguously that the invasive pathogen Batrachochytrium dendrobatidis (fungus), introduced by humans, is the main cause of amphibian species decline. His major achievements on amphibian-associated chytridiomycosis (fungal disease) include the first and the most thorough description of the evolutionary history of Batrachochytrium dendrobatidis, the role amphibian trade played in distributing the pathogen, the Out of Asia hypotheses and identification of the genetic variants behind global amphibian declines; identification of a new species of Batrachochytrium responsible for salamander declines across Europe; development of global and regional risk assessments for chytridiomycosis; and the development and implementation of mitigation strategies for chytridiomycosis. In addition, Matthew has made significant contributions to the development of diagnostic tools and improving the application of the 3Rs for research on chytridiomycosis. Matthew is a generous and respected collaborator, supervisor and mentor.
