Amanda’s research focuses on small population recovery, with a particular focus on Extinct in the Wild species.

Amanda's work also looks at other species where ex-situ management (i.e. under human care) is an important part of their conservation strategy. Amanda’s current research aims to aid recovery efforts for the Extinct in the Wild sihek (Guam kingfisher) by determining how individual health can influence population processes for the ex-situ population, and what this means for species conservation and individual welfare. As part of this project, Amanda collaborates with the Association of Zoos and Aquariums, Guam’s Department of Agriculture, as well as the Disease Risk Analysis and Health Surveillance (DRAHS) team at ZSL and the Royal Veterinary College.

Amanda also has research interests in the changes populations of wild species undergo when they have been at small population size and/or maintained ex-situ and what this may mean for these species’ recovery potential.
