I'm a research assistant with an interest in amphibian conservation and systematics. I studied at Macquarie University and UNSW Sydney (Bachelor of Biodiversity and Conservation (Honours)), and have worked at the Australian Museum since 2015.
Having been involved in a number of projects focusing on 'lost' or otherwise very elusive species, I am particularly interested in technologies that enable greater detectability of priority species that are difficult to detect using traditional survey methods. Currently I am working on detection methods for threatened frogs using invertebrate-derived DNA (vertebrate DNA recovered from the meals of parasites and sequenced to identify and detect the host species).
In addition to detectability work, my role involves undertaking amphibian survey expeditions in Australia and Southeast Asia, and spending a lot of time analysing frogs' DNA and calls to help understand amphibian diversity. I am also a program officer with the IUCN Amphibian Red List Authority, which sees me assessing the conservation status of Southeast Asian amphibian species for the Red List of Threatened Species.
Program Officer, IUCN Amphibian Red List Authority, since 2015.
