Key Info

  • Position Title
    Research Assistant and FrogID Validator
  • Section
    Herpetology Collection
    Australian Museum Research Institute

I have been with the Herpetology team since 2017, firstly as an IUCN amphibian red list authority intern, assisting with red list assessments for South East Asian amphibian species, as a research assistant, participating in several amphibian field surveys across NSW, and more recently as an honours student and FrogID validator.
I have a passion for amphibian conservation, particularly disease management. My recent honours project in association with the University of New South Wales and the Australian Museum Research Institute investigated the disease dynamics of the amphibian chytrid fungus in the greater Sydney region.

In my current role as a FrogID validator, I work behind the scenes of the Australia-wide citizen science project, FrogID. I validate frog calls across 6 of Australia’s states and territories.
